Go around the problem instead. Can you spare one extra nibble of RAM?
If so, store your score as 5 BCD digits instead of in binary, and put the
6507 in BCD mode to do your score computations. That's the smallest
ROM-consumption way to do it, and it also lets your score range up to a
full 999,990 instead of stopping at 655K.
To think even further outside the box, you could just display the score
in hexadecimal :)
