I seem to remember there used to be wording to the effect that an
ICC/IPC needed to include a "representative sample" of the PTS checkride
tasks. I can't remember if that was in the PTS itself or part 61/91

That wording is in 61.57(d). If the PTS is advisory and not binding, then
the CFII's discretion will not have been significantly hampered.
