In this case, scaling to a unit will generally preserve sorting, but if it were to not, some very nasty bugs will jump out. Whether the array is sorted is essential, since it allows the use of a fast binary search algorithm to find indices corresponding to values (one which must run every time a fixed coordinate is altered in the FilterNode).

We can do checks to correctly propagate ArrayFlow.is_sorted, and we should.
