Is your drum scoring on the surface where the magnets contact (face) or the linings contact (circumference)? Whether either can be resurfaced I don't know.
We bought a 2010 SD17 in 2012. Turned out that Dexter apparently had a problem with one batch of
brakes from around that time. Both
brakes failed (one at a time). They would hang-up, not fully release. Problem was caught by noticing HOT hubs. Supposedly it had something to do with the magnets. Odd thing was that slight move backwards after stopping would pop them loose. (Why backing up would release the magnets?) Any way, we caught them before any damage to the drums. IIRC the whole brake unit (without drums) was not much more than the magnets by themselves, somewhere around $50. And replacing the whole unit took care of any mechanical problems that might have been in there, also. Have had no problems since.
Getting the old brakes off was a b*tch. The nuts that held the backing plate on the
axle were hard to get at and a little rusty. They bolts were just pressed into the backing plate and would strip in the plate before the nuts broke loose from the rusty bolts. Finally had to get a nut cracker which barely fit on the nuts.
Good luck.
