The other approach would be to accept that some unit tests depend on sort

Is the result deterministic? And is it still mathematically correct?
Deterministic: yes.
Mathematically correct: Sort of, one Piecewise condition goes from
Ne(1/s, 1) to Ne(s, 1).
For SymPy, it is equivalent; for the human reader, it might be
considered mathematically "almost equivalent" due to the singularity at s=0.
With a mathematically incorrect result I'd assume a bug in the
integration algorithm anyway.
Is there a third, better approach?
I indeed came up with third approach tonight: keep the existing sort
order and remove the comment that it is outdated.
Not better, but correct enough to have a place on the list of options.
