Take a look at your browsers JS error console. You will notice something saying something like getScore is not defined. You have defined getScore. The problem may be because you haven't closed the head tag. Depending on the browser your JS functions may not be defined until you close the head. It is best to only have one head at the beginning of your document instead of switching from body to head because it is more acceptable and it stops these sorts of things from happening.
I didn't take a long look at your code so it may be something else but that's where I'd start.

just passed by when searching around for online quiz. according to my experiences, maybe you can try the sweet app Hot Potatoes to do the easy job than just coding. actually, in order to avoid any javescript errors in browers, i usually take flash-based quiz for online use (for flash, QuizCreator is recommended). i hope my suggestion helps.
