Example

These are the first 24 finite permutations. The inversion sets interpreted as binary numbers on the right form the sequence A211362, which is not monotonic:

This is the same list ordered by the inversion sets, so the right column is monotonic now. The left column is the beginning of the permutation p, i.e., this sequence:
No.  permutation   inversion set  A211362*p
00     1 2 3 4     0  0 0  0 0 0     0
