Those are not scratches, but rather markings from some sort of grease. It's white-ish and you can scrape it off with your nail.

All coupes suffer from this. Mine is at its worst during winter time. Summer time I don't see any marks.

I am not sure that replacing the oem seal with oem will fix the issue. I know there is a company that has a fix for this. its a piece you attach to the oem seal. Can't recall the name of the company, I'm sure little googling will yield results.
