Kenneth,
Below the cut is my example implementation as I understand your
requirements.
Note that the "compare" routine uses $a and $b which are "special" to perl
sort routines.
Also the compare routine is written for obviousness rather than for brevity
or elegance.

In this very particular case you should consider turning off the warning,
maybe limiting it to the block.

Hi;
I'm having trouble understanding the built-in Perl sort with regards
to mixed numbers and strings
I'm looking at http://perldoc.perl.org/functions/sort.html
I have an array that I want to have sorted numerically and descending.
The array is composed of elements that loo
g to a number using a thing from Scalar::Util.

Hi;
How do I call the built-in Perl sort function on an array of strings
where the string is composed of one or more digits, followed by a tab
which is followed by a string and I want the results to be sorted in
reverse numeric order?
I looked at http://perldoc.perl.org/functions/sort.html
