I'd use the 'service jack' adjustment to turn the score motor off, so you can turn it by hand and see where the relay is dropping out early.

Quoted from ArgosySK:

I suspect that the normally closed relay on the motor need to be a bit tighter. I suspect that one of the nibs on the motor is slightly worn and it doesn't make good contact.

You may be able to tell this is the case if the missing score always occurs at the same time during the score motor rotation, like:

SCORE - SCORE - ?? - SCORE - SCORE
