illegal forward handing

[hobbes]

This play was recently covered on this board, but under illegal forward pass. This is what happened last night in our Middle school game. Thanks to this board, myself and our WH had read the thread on this and were able to sort it out (I think we got it right anyway). My question is about my mechanics of the play as LJ.

0-0 game. A has the ball 3rd and goal from B's 9 with 7 seconds to go. A1 runs a sweep to my side and breaks a couple tackles, gets to the two and starts to get tackled but still moving forward. As A1 struggles, A2 steps in front of him and takes the ball from him at the 1 and backs into the end zone. Myself (LJ) and the WH drop a flag at the 1. The WH very clearly explains to the B captain that if he declines the penalty, they will lose since time had run out, or he can move them back 5 yards to the six with one more play. A decides to try a field goal and misses. 0-0 tie since this was a middle school game and the league doesn't play OT. Very fun ending and glad we had read about Illegal forward passing at the end of a quarter. It ended up being very confusing for the fans and coaches.

My question about the mechanic is whether or not I should signal TD or not after dropping the flag, or just stop the clock (which had run out)? MY feeling is that I should have given the TD sign.
