Default Cylinder scored ?

I would just like some second opinions on this from more knowledgeable people.

Anyway Took the head of to fit my new one and was greeted by this on piston 3.

Does this mean that my rings are gone and it needs replacing or is it ok to put the new head on and run it ?

I can't feel the lines with my fingernail except one small scratch. Some one said they could be oil staining and therefore ok?

The others cylinders look fine, I can still see the cross hatch pattern from the honing.

I do have a spare block in the garage, but its been stood a long time and is dirty, whats my best option ?
Thanks again for the help

I had scoring like that where I couldn't feel it but I could see it. My machinist said that he could hone it out, but I was getting it re-bored to 75.5mm anyway.
