+1 If you want to save the frame, I would look into brazing inside threaded tubing (threaded spacers) into the holes and then filing the outside edges flat. You could mount a rack directly to them. If the holes aren't big enough for that, perhaps you could braze in tubing as suggested and then use a nylok nut on the inside.
I'm sure it was disappointing to see that, but I wouldn't give up on the frame just yet.
