I can't see any problem with that.
Clean up the light scoring with emery paper and a good wash off/blowout to remove any particles.
 
Scoring on the axial surfaces / ends has little to do with the function of the pump. The outside cookie shaped surface is more important as that is what pushes the oil. I would run it as-is.
 
Probably too expensive/tricky to bother with, but could you send it to an engineering shop to pressure test it to see if it's still within the acceptable range of tolerances?

Anything to do with the oil system being under the weather would give me The Fear, but I acknowledge that other opinions are available.
 
Thanks hope to get engine back together in the next few weeks will keep an eye on it.
 
To me the wear pattern indicates wear on the shaft and its not running true, could be costly if it goes altogether !!
 
I will be replacing them.
