currieddog is right. It's likely your A/Alternating relay isn't firing:

It should change state each time the 0-9 or Match Unit takes a step, which should be each time 1 point is scored.

The A/Alternating relay should have 5 Make/Break switches mounted to it. You should be able to find all five on your schematic and match them up using the wire colors. It's hard to tell from your photo but it looks like the jumper may be wired to the two outside leaves of the same Make/Break switch. If that's the case it's hard to imagine that it was meant to be there since wiring the switch that way would usually defeat the purpose of the switch.

I think your two jumpers are factory. Have a look at the two switches in the red box:
