Proof of concept works.
Just be careful, after submitting the top score (12400 $, I don't know if it is related or not) the alert telling me I had submitted looped (I clicked OK, and the alert would pop up again).
Maybe you're missing some "Trigger once while true" condition somewhere.
Tested in firefox 6.0.2.
Else good work, especially in 3 days <img src="smileys/smiley1.gif" border="0" align="middle" />
