Scratch and scored front wheel hubs

[bloody hammer]

I was knocking out the bearing races on a front hub today and I guess I had the screwdriver (I know, I know) angled too much at some point and ended up gouging the inside of the hub. I know it's hard to answer without seeing the damage but generally speaking... how big of a deal is this?

No real problem - just drive the new races in and get on with it?

Medium problem - but can be fixed with emery cloth or Dremel or a honer?

Huge problem - it will have to be replaced?
