in reply to Comparison result capture???

You're assigning the split results to scalars but not using those scalars in the map block, which seems a bit, well, odd. What's up with that?

As for the "last result" idea, foreach (which is spelled "for" by all good monks) will often serve the purpose of avoiding duplicate expressions:

$_ and return $_ for $a_parts[$_] <=> $b_parts[$_];

I've also run into odd restrictions on no strict and I really wish I understood what was broken by accident and what on purpose WRT that.

Finally, I'll take off a fractional style point for using a map block where you really meant foreach....

    speaking of odd, your use of for for a 1 element array is pretty novel all in its own right.

      I wish I could say I'd invented that, but I stole it from Tom C. I don't know whether he stole it in turn....

    Didn't you mean 
    my $x;
($x = $a_parts[$_] <=> $b_parts[$_]) && return $x
   for 0 .. $#a_parts;

    You're using $_ too many times.

      I'll grant you that my code uses $_ with more than one meaning, and some people may not like that. But it's clear enough to me. Seems to work, too.

    Oops! I meant to split $a and $b into @a_parts and @b_parts, which makes a lot more sense. I have submitted a change request to the editors.
