You can't have 2 hash keys as 'es' so you need a 2nd level to your %identifier hash
eg $identifier{$pins2}{$w2} = $h2

#! /tools/perl/5.8.8/linux/bin/perl
use strict;
use warnings;
use Data::Dumper;

# Source script
my $report = $ARGV[1] || 'report.txt' ;
my $waiver = $ARGV[3] || 'waiver.csv';
my $result = $ARGV[5] || 'result.txt';

# Set up a hash to receive the information
my %identifier = ();

# Read the violations file into the hash
open my $filter, '<', $waiver 
     or die "Could not open $waiver : $!";
while (my $vline = <$filter>) {
  next unless $vline =~ /\S/; #skip blank lines
  $vline =~ s/^\s+//; # trim leading spaces
  my ($pins2, $w2, $h2) = split /,/, $vline;
  $identifier{$pins2}{$w2} = $h2;
}
print Dumper \%identifier;

# Read input file line by line and compare 2 files
open my $input, '<', $report  
     or die "Could not open $report : $!";
open my $output, '>', $result 
     or die "Could not open $result : $!";

my $header = 1;     
while (my $wline = <$input>){
  # skip checking the heading text   
  if ($header == 1){
    print $output $wline;
    $header = 0 if ($wline =~ /-------/);
    next;
  }
  
  # delete the contents if matched  
  # undef is leading space
  my (undef,$pins1, $nets, $w1, $h1, $slack) = split /\s+/, $wline;
  if (exists $identifier{$pins1}{$w1} 
          && $identifier{$pins1}{$w1} >= $h1) { 
    # skip matched line
    print "DELETED $wline";
  } else {
    print $output $wline;
  }  
}
close $filter;
close $input;
close $output;
