I am trying to sort a hash of arrays that is similar to the example

I have a hash of arrays that I want to sort, first by the first

elements
of the array (for sorting and without regard to case.

%HofA = (orange=>['ZZZ', 'ANDY'],
           red=>['AAA', 'AL'],
           blue=>['mmm','Betty'],
           yellow=>['aaa', 'ZEUS'],  
           green=>['DDD','Mary Joe']
           violet=>['MMM','Hugo']

my @ordered_keys = sort { $HofA{$a}[0] cmp $HofA{$b}[1]
                                           ||
                                           $a cmp $b } keys %HofA;
I believe that will do it.  See if that gets you going.
