By the way, if you wanted only up to one of those conditions to match, then you don't need all this complication with a string of zeros and ones. Just have the key be a single number you just compare with spaceship. Something like this, untested:

... sub list_sortflags { my($s) = @_; my @networks = ...; my $network_string = ...; my $k; if ($s->{user} =~ /LadyAleena_($network_string|TV)/ && $s->{name} !~ + /TV/) { $k = 1; } elsif ($s->{user} =~ /LadyAleena_($network_string)/ && $s->{name} =~ + /TV shows$/) { $k = 2; } elsif ($s->{user} eq 'LadyAleena_TV' && $s->{name} eq 'Premium TV sh +ows') { $k = 3; } elsif ($s->{user} eq 'LadyAleena_TV' && $s->{name} eq 'TV shows') { $k = 4; } ... elsif ($s->{user} eq 'Lady_Aleena' && $s->{name} =~ /(Followers' bus +inesses|List subscribers)/) { $k = 11; } else { $k = 12; } $$s{sortflag} = $k; } ... sub list_compare { my($a, $b) = @_; return $$a{sortflag} <=> $$b{sortflag} || my_sort($$a{name}, $$b{name}, "article"); } ...
