Originally posted by techsouthInteresting point, I hadn't thought of it in that way. You might be right, I have no idea.

According to the rules of chess, he would get the win regardless of whether he sees that he has you in mate. So a timely post-mortum would have probably resulted in a dispute that he would have won.
Edit - Although knowing this is just a curiosity for me. If I was mated and my opponent didn't immediately say anything, at the least I'd probably refrain from making a quick move. And I might even decide to just announce the mate against myself and say good game. Yeah, I know, I'm beyond help, lol.

In the case, a person was in what appeared to be a hopeless situation, made a move out of dispair and shortly afterwards resigned. After closely looking at the board it was realized the move had put his opponent in checkmate. The ruling was that he wins with the checkmate, because anything done after putting your opponent in checkmate is irrelevant, including saying "I resign".
I'm sure the statute of limitations has run out by now on your game, but I don't know when exactly that is. Possibly after posting results or after next round pairings. If you do find the exact point that reversals are not allowed, I'd be interested too.
I found a thread on the USCF forums that discusses the same basic question. There is a clear consensus that player A, who delivers the mate but doesn't realize it, has indeed won the game, even if play continues. (One poster to the thread disagreed, but I think his reasoning is faulty.)
Concerning when a decision would cease being reversible, there were a few different opinions. The one that seemed to make more sense to me is that if the error was discovered before the next round's pairing, the result would be reversed for both tournament and rating purposes. And if the error was discovered after the next round's pairing, the tournament result would be allowed to stand, but the result would be reversed for rating purposes. Regarding this reversal issue, it seems that the TD has some lattitude on how to handle the tournament result aspect of the problem.

Edit - P.S. And note that in the USCF thread, one of the posters giving opinions is Tim Just, who is a co-editor of the current edition of the rule book!
