if your tint is just a few days old, baka hagod lang yan nung squeegee na nag mark. let it stay for a week or so then try to wipe it off clean, hopefully matanggal pa yan.
otherwise, if you really feel with your fingers an uneven depressed portion on the scratch, then that's definitely unrepairable. but you should claim that against warranty from your tint installer.
That's what I did, i just had my tint installed and the installer used a steel "paleta" instead of a rubber one, daming scratches, palit sila sorry nalang sila buong windshield yun.
