I'm too tired to walk through this like I normally would but download FCEUXDSPOMGWTFBBQ*, load your ROM, open the hex editor, set it to NES memory, find the score in memory, set a write breakpoint, kill something, the debugger will snap and you can read the instructions to find out what's going on. Hopefully that will work, if not I'll take a look at it tomorrow.
