Ouch, that doesn't look very good. It shouldn't cause any catastrophic issues, so you can plan for a rebuild down the road a little ways. It looks like some signs of detonation on your pistons also, there are some craters in them.

If your fingernail catches them they are usually at least .002" deep. If they are less than .005" deep you could bore it .030" over (since you are .020" over already) and get rid of the scratches. Can the stock block take .030" over?

I don't think honing it with the piston still in is a very good idea, if I fix it I'll fix it 'right'

I think the craters are from the same thing that caused the scratches, none of the other cylinders have them

If the block comes out it's getting sleeved, .020" is already risky enough on this block.
