Store all those little subroutines in an array.

If I understand you correctly, that would entail changing my original code only with respect to what gets assigned to $mysortref: 

my $mysortref = do {
    my @littlesubs = (
        sub { lc($data{$a}[0]) cmp lc($data{$b}[0]) },
        sub { lc($data{$a}[1]) cmp lc($data{$b}[1]) },
    );
    sub {
        foreach my $sub (@littlesubs) {
            my $result = $sub->($a, $b);
            return $result if $result;
        }
    };
};
@results = sort $mysortref (keys %data);

But I don't see where that gets me any closer to solving my original problem. To change the sort formula I still, AFAICT, have to change the hard-coded subs which are now elements in @littlesubs.
