Which issue does this PR close?
Related to #7794
Rationale for this change
While debugging #7794 (which I think is a bad plan) the lack of Sort exprs caused very strange behavior that made it harder to debug.
Specifically, the merge code ended up passing bad indices to
interleavewhich resulted in a panic far away from the source of the problem.What changes are included in this PR?

Yes by existing tests
Are there any user-facing changes?
No, only easier to debug failures
