Check the schematic on ipdb.org. You'll see that the score motor is powered through any of quite a few switches. You need to see which one is closed when it should not be. Easiest way to do this is to block the switches one-by-one with a piece of cardboard until you find the problem switch.
Alternatively, when you start the machine up, see if any of the relays whose switches are inline with the score motor energize.
