In the seventies, the 042 prefix on the SSN indicated the Form SS-5 was filed by a CT resident.
Agreed.
Obama's biography indicates he traveled as an unaccompanied minor from Indonesia to a U.S. port of entry in 1971.
Maybe you can post or quote the relevant passage in Obama's biography to back up that statement. Even if you are correct about what his biography said, we know that his biographies are not necessary reliable, as they contain many statements that are inconsistent with other factual evidence.
Barry Soetoro, son of Lolo Soetoro and born in Honolulu, HI, was enrolled in an elementary school administered by a subsidiary of the Catholic Church as an Indonesian national..
There is no real long form Hawaiian birth certificate to prove that Barry Soetoro - or even Barack Obama II - was born in Honolulu, Hawaii. (What you probably have seen is an Indonesian school registration form which is based on info passed to the school through Lolo Soetoro and/or Stanley Ann Dunham.) Barry was not the son of Lolo, rather the (adopted?) stepson. He did begin school in Indonesia attending an elementary school administered by the Roman Catholic church (with St. Francis in its title) for two years, then switched to an Indonesian school which featured a Muslim religious curriculum. (There is no logical connection between his attendance at an elementary school in Indonesia administered by the Catholic Church between ages 6 and 8 and his CT SSN issued to him at age 15.)
The U.S. Government defines unaccompanied minors abandoned at a port of entry as children with foreign nationality who do not have a parent or legal guardian to accompany them. The pilot or a flight attendant cannot be assigned guardianship for purposes of clearing customs. The U.S. Government considers the child to be abandoned.
That may be the US Government policy today, but you have no evidence to show that the same policy was in force c. 1971. Furthermore, you have no documentation that young Barry was indeed classified as a minor with foreign nationality without parent or guardian accompanying him at that particular point, since you have no copies of government paperwork from such an incident.
In the seventies, there were two contractors with HHS to administer legal services for unaccompanied minor children abandoned at a port of entry. One of those contractors was headquartered in Connecticut.
You have no sources to cite to prove that there were any such contractors at all at that time, let alone one headquartered in Connecticut. (Incidentally, if, hypothetically, young Barry at that time was referred to a provider of social services, that provider would probably have been a Hawaii state or local agency, not a federal contractor headquartered in Connecticut.)
Here's a good primer on the subject: The Changing Face of the Unaccompanied Alien Child: A Portrait of Foreign - Born Children in Federal Foster Care and How to Best Meet Their Needs.
The paper to which you linked, published by a Catholic Church organization, has no historical references to the time frame we are discussing, and is therefore irrelevant to the issues here.
No, that is not true. from the SSA website:
"Since 1972, when SSA began assigning SSNs and issuing cards centrally from Baltimore, the area number assigned has been based on the ZIP code in the mailing address provided on the application for the original Social Security card. The applicant's mailing address does not have to be the same as their place of residence. Thus, the Area Number does not necessarily represent the State of residence of the applicant, either prior to 1972 or since."

"The U.S. Government defines unaccompanied minors abandoned at a port of entry as children with foreign nationality who do not have a parent or legal guardian to accompany them."
This is from the 2002 act that you linked.
"The act defines UAC as “children who have no lawful immigration status in the United States; have not attained 18 years of age; have no parent or legal guardian in the United States; or no parent or legal guardian in the United States is available to provide care and physical custody.”
Obama had grandparents waiting for him the Honolulu. He made an earlier trip by apparently by himself the summer before he returned for good. It was for an interview at his new school, he went to the interview with his grandparents but their is no mention of his mother being there.

Got anything from the 1970s?
"In the seventies, there were two contractors with HHS to administer legal services for unaccompanied minor children abandoned at a port of entry."
Can you document this?
