FF to the 2nd half. AP throw in for B, ball goes back and forth before B1 finally scores. Horn sounds, because A coach is requesting a C.E.

In the OP, it seems to be that the free throw would be a part of the 2nd quarter. In your situation, (which I can't imagine happening) it would clearly be a part of the 3rd. And I don't guess it really matters one way or the other.
