Ehh accidents happen. EX. I put 4 tires on my car the other day, and I scratched every wheel will dismounting them.

Some tires are a bitch to take off, trust me, I've mounted hundreds of thousands of em. But I can re-paint mine, and they'll look good as new.
How deep are the scratches? what kind of tire machine were they using? if it was a table top one, I hope they clamped the rim from the outside.
If it was me personally, and they weren't very visible, I wouldn't worry about it.
