Quoted from Robotworkshop:

After reading up on the scoring I think I need to double check the adjustments on all the contacts for the number 9 positions. If one of those contacts isn't making a connection or not opening then that could be part of the problem. Should have some time tonight to check them out.

Two reels scoring at the same time is almost definitely a 9 position switch. The 100s not carrying over to the 1000 could be a 9 position switch on the 100s or also a switch on the 100 point relay that supplies power to the 1000 reel at that point.

Quoted from Robotworkshop:

Yes! I made progress this evening. No more two reels scoring at the same time. All of the player 1 score reels are working perfect now and carry over as they should. There are still issues with the player two score reels. Those no longer have the problem of two reels going at once. However, those reels don't always reset to 0 and the carry from the 100's to the 1000's doesn't work. I've cleaned the 9 position switch for the 100's and as far as I can tell that is adjusted properly.
Going to check all the associated relays and wiring to see if anything is out of place.

Check the switch on the 100s relay that sends power to the 1000s when the reel is going from 9 to 0.

The reset problem can be bad zero position switch adjustment.
