First thing to do is confirm that you have 25 VAC for the coils. An easy way to do that is to turn the score motor cam counter-clockwise a few degrees until it is out of the home position. At that point the motor should fire up and run the cam to the next home position.
If the score motor doesn't run, check the 25 VAC fuse and fuse holder and make sure all is well there.
