If someone would tell me how to put one in then I'd shut the hell up about it already ffs.

I have a feeling that even if someone told you, you wouldn't know how to do it.

I don't know how this game is structured, but it seems like all you'd have to do is make the game direct you to a frame with a stop action on it that has buttons for submitting your score or restarting, rather than having it direct you to a game over frame whenever you crash. The submit button would direct you to the original game over screen, which would submit your score, and the restart button would just send you to frame one of the movie. But it's hard to say without having seen the FLA.
