Scanning with a scanner or enlarging with an enlarger is the same thing: make a positive from a negative.
Um...if you are trying to deal with removing scratches then scanning versus enlarger prints is two entirely different problems.
I'm guessing something is being lost in translation here so I'm gonna let it go.
As for the OP, scratched negatives suck but be glad you do have the digital option to correct them. The healing brush is probably the best tool to deal with it but if you want to try a potentially easier solution, check out the content aware fill features in PS. I think they started getting pretty good in CS5. If your version is earlier then you are stuck with healing brush.
It's ok, I just wanted to say that it's not a different story.
In the darkroom, the paper to make the prints is negative, like the negative film. Negative + negative= positive.
With a scanner you can scan a negative to make it positive, same as negative paper in the darkroom.
For me is the same thing to shoot digital or film, but i print digital. PS is more versatile and repeatable.Especially for the scratches and Silver EFX pro.
