If by "slight scoring" you mean something that won't easily snag a fingernail and there is no sign of heat discoloration on the rear main journal then I would say go for it. Do any polishing with very fine emery cloth. Polish only in the direction of rotation.

Of course, there are "slightly spun bearings" and "very badly spun bearings" and you must make sure that you can get the proper clearance with plastigage so check the rear main cap very carefully for heat marks and stress cracks. I know the crank is still in it so you can't check the block but if the cap is OK I'd say it's worth rolling the dice. The service manual will tell you if the rear is also a thrust bearing and if so then you must check end play too.
