So it turns out that it wasn't the cluster compatibility that I missed, but that the data center compatibility level needed to be updated to 3.6 as well. I just didn't read the error message closely enough. RS> So the upgrade failed, but the 4.0 rpms were installed, so the engine won't RS> start. How can I fix the compat level (or delete Default cluster)? For the record, I ended up using 'yum history' to roll back the updated packages, and was then able to start the engine, change the datacenter to 3.6, and re-run setup successfully.
