Check at 13.5 on the schematic for Top Eject relay. There is a make/break on the score motor that could be the cause.

You may have some "floating" contacts. Crimp the contacts on the relays involved with a pair of needle nose pliers.

And if not, check the whole sequence leading up to the two bonus relays at 15 on the schematic.
