Here is another way to do this... 
#!/usr/bin/perl -w
use strict;
use List::MoreUtils qw{uniq};

my $sample = "A-E-H-L";

my @options = ( "A-B-F-G-H-K-M",    # idx = 0
                "A-E-G-H-L",        # idx = 1
                "A-C-E-G-H-J-L",    # idx = 2
                "B-F-H-K",          # idx = 3
                "A-B-F-G-H-K-L",    # idx = 4  
                "C-H" ,             # idx = 5
                "A-E-H-L",          # idx = 6
                "H-E-A-L"           # idx = 7
              );
              
my @indicies = find_indexes (\@options, $sample);
print "sample $sample occurs in indicies: @indicies\n";
            
sub find_indexes 
{
   my ($aref, $template) = @_;
   my @indicies; 
   
   my @patterns = $template =~ /\w+/g;
   my $regex = join ("|", @patterns); # "OR"  is easy with regex
                                      # "AND" is hard
   
   my $index;
   foreach my $line (@$aref)
   {
      my (@matches) = $line =~ /$regex/g;
      push @indicies, $index if (uniq (@matches) >= @patterns);
      $index++; 
   }
   return @indicies;   
}

__END__
Prints: sample A-E-H-L occurs in indicies: 1 2 6 7
