See, that's the problem with your logic. You've got things turned around. You're using the theory to explain the evidence, not the evidence to explain the theory.
If you can demonstrate that a vestigial organ once had a purpose, then you can use it to contend that under evolution it was selected for.

I was starting from the premise that the prior function of the vestigial organ was known.
All the available evidence indicates that contrary to popular belief, the appendix is not a vestigial organ. It appears to have first showed up in Old World Monkeys and has become more important as we have evolved. It appears to play an important role in the immunosurveillance of the GI tract.

What explains homosexuality?

That is a tough one, but not something easily explained by creationism, either.
It is possible that there is a survival advantage to children of families in which there were gay adult relatives without children of their own. This would be because if something happened to their own parents, this childless gay relative would be more willing to take care of them. If all the other adults had their own children to take care of, they may be less willing to care for orphans. So maybe there is a survival advantage to having a small percentage of childless adults around.
This link floats a few theories:

Homosexuals aren't incapable of having sexual relationships with the opposite sex and there is no evidence that I have ever seen that they won't engage in these behaviors with the opposite sex just to have children. I know many gay men who married women and have kids with them.
Throughout human history, by and large, whether females reproduced or not was not something that they had much say in. For the bulk of human history, we have been relatively powerless and often times considered property. Whether we reproduced or not was determined by men, not women. So as long as a female homosexual was attractive enough to a male, she would reproduce. That probably was sufficient to keep the genetic determinants of homosexuality alive in the gene pool.
