Would it be easier to just assert that the count of $expectedDocuments and $values is equal and then loop over $expectedDocuments and assert that each of its elements exists in $values?
I realize the only scalar is 4 at the moment, but this seems like it could be fragile if additional scalars were added to the test data.

I shamelessly copied this from DistinctFunctionalTest, so I had to double-check what it does. This method generally sorts scalars to the top and non-scalars to the bottom, but each group is sorted within itself, so adding multiple scalars shouldn't pose an issue. Non-scalars are encoded to JSON before sorting, so they are sorted by their JSON representation.
