Yep, common issue since the construction of the blue score counter is different than all the others, and is exercised infrequently.

Okorange's advice is spot on.

The spring not forcing the ratchet action just sounds like dirt. The relay armature spring could be worn, but there should also be an adjustment in that coil's position, if I recall correctly. Take a close look there.

They all open up at some point, speaking from memory. If it doesn't there's something maladjusted.

The game treats that as a continuous stepper. The opening and closing of the switches determines when it stops. Examine which switches are open at 292 and adjust so that it opens later. It is probably only two clicks off.

It will automatically ratchet back to initial position if not on index.
