It does look like a scratch to me - whether she accidentally hit something (a low branch of a bush in the yard) or did it with her own nails or something else.
Watch for any redness, puffyness, swelling or discharge. You might want to call your vet just to ask if there any other signs that you should watch for, too. Since it isn't really distorted or swollen, I'd probably leave it, but I'm definitely not an expert in this area. Anything near the eye would make me more nervous than elsewhere.
