Thanks in advance.
You can't do anything about the scratch anymore, so your best bet is to send it to the caste center and hope they fix it.
How did you scratch it? Did you drop it? Because if you did, there might be damage on other components as well. If you didn't, then there's nothing to worry about, just a scratch is no big deal.

I'm having the exact same issue, it's most noticeable when typing, sometimes when scrolling web pages it zooms in or out like I'm using two fingers, and my N7 is in perfect condition, with no damage on the screen at all. If they're going to just fix it you shouldn't have an issue, replacing it completely they may give you some trouble.
It seems that N&'s built during September of 2013 have this problem. Check your box for the build date and see if it is the same. Thats exactly what I have. When I type it hits too keys. For example it will hit c and space. Hopefully they replace it. Thanks though
