That one is actually rather clever....
Most of your examples, however, look like you are attempting to bandage some
poorly designed code upstream. (Perhaps not, but writing logic built around
<=> or cmp as a control flow is rarely a good idea.)

This was your lone example that actually made some sense, and the only
non-standard answers (by which I mean conventional control flow methods) I
can think of are:
$x = ($default,$a,$b)[$b<=>$a]; # Much like I did before
($x) = sort { $a <=> $b or $default } ($a,$b);
# Since <=> and cmp were created more-or-less specifically for sort
The former is faster than the latter, but neither are as quick as the more
conventional structures.
