I think I just need to disable sort. Because there is a () group, we
don't need a Sort in the plan to exercise the bug.

Committed to master. I'll backport if the tests stabilize. I'm on
vacation now and will return on the 5th, so hopefully we're in a
reasonable state until then. If not, I can just revert my fix and deal
with it when I get back.
