Generally speaking, If it catches with a fingernail its too deep.
That being said, it might be best to take it to a machine shop and let them see it in person.

Based on the pictures I would consider it trash. I've seen scoring lighter than that, that I would refuse to work with.

Yep, let that one go... it will never be right. Anything can be fixed, but it just isn't worth the cost in this case.
