Yet Another Shot Clock Question

[rainmaker]

Well, I'll probably never need to know this again, but today, I wished I did.

Possession arrow points to Team A. Shot clock winding down. A1 goes up to shoot. Before she releases, B1 goes up to block. At the top of the jump, the ball is trapped between the four hands of A1 and B1, just as the shot clock buzzes. Now what?

Partner and I had absolutely no clue, but we figured no one else did either, so we gave the ball to A with a new shot clock. No one complained. A won by 30, so we didn't give the game away. But I'm wondering what we SHOULD have done. NCAA rules. Would NAIA be different?
