Try this one:

#!/usr/bin/perl

use strict;
use warnings;

my $target = 'PEARLYGATES';

for my $word ( qw( EASYPEASY GATES PERL ) ){
  if( check_word( $target, $word ) ){
    print "$target contains $word\n";
  }else{
    print "$target does not contain $word\n";
  }
}

sub check_word {
  my $target = shift @_;
  my $word = shift @_;

  my @target = sort split //, uc $target;
  my @word = sort split //, uc $word;

  my $tidx = 0;
  for my $char ( @word ){
    while( $char gt $target[$tidx] ){
      $tidx ++;
      return 0 if $tidx >= @target;
    }
    if( $char eq $target[$tidx] ){
      $tidx ++;
    }else{
      return 0;
    }
  }
  return 1;
}
