You can use Sort::Maker or Sort::Key to generate efficient sorters on the fly: 
# untested!

use Sort::Key qw(multikeysorter);

my @types = qw(int str str str str int);

sub gen_sorter {
  my @ix = map abs($_), @_;
  my @t;
  for (@_) {
    my $t = $types[abs $_];
    $t = "-$t" if $_ < 0
    push @t, $t;
  }
  multikeysorter (sub { my @k = split /\|/;
                        $k[5] =~ tr/><//;
                        @k[@ix] },
                  @t);

}

my $sorter = gen_sorter(1,2,-3); # order by the first key,
                                 # then the second and then,
                                 # the third desc
my @sorted = $sorter->(@data);
