You need to see what the compression is in all of the cylinders.
If the rings are that bad there might have been score marks on the cylinder walls that he should have seen when the head was off.
I would hope that he would have cleaned the carbon off the top of the pistons and checked all of the cylinder walls when the head was pulled.
You really shouldn't be driving it with a cylinder misfiring.
+1 on what JimLev said as well as most everything else stated above.

I don't know how long you can wait but I will have a good running 528i motor available as soon as I can get a chance to pull it. I'm doing a swap to a built up M54 engine and the car is currently off the road for the winter. I would still get a second opinion on the diagnosis before going further.
