I have 2 files that I am trying to compare. One is sorted the other one is not(and includes some info that I really don't need) ie

//snippet of sorted for File1

acp.lanier.com = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY = tcp.lanier.com) (PROTOCOL = TCP) (HOST = st.lanier.com) (PORT = 1533) ) ) (CONNECT_DATA = (SID = utl) ) )

//File 2 unsorted

/want to ignore this part

############## # Filename......: # Name..........: # Date..........: ################ /

sdcht.lanier.com = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (COMMUNITY = tcp.lanier.com) (PROTOCOL = TCP) (Host = sb.lanier.com) (Port = 1521) ) ) (CONNECT_DATA = (SID = sdcht) /want to ignorthis(GLOBAL_NAME = sdcht.lanier.com)/ ) )

I obtain the general pattern and input into an array. sort the unsorted array. and the compare the files and print what is different. If anyone can tell me where I am going wrong in my logic or coding. 
 #! /u/ss/bin/perl -w

$pattern = qr/
        ([^=]*=\s*\(DESCRIPTION\s*=\s*
        \(ADDRESS_LISTS\s*=\s*\(ADDRESS\s*=\s*
        \(COMMUNITY\s*=\s*[^)]*\)\s*\(PROTOCOL\s*=\s*TCP\)\s*
        \(HOSTS\s*=\s*[^)]*\)\s*\(PORTS\s*=\s*\d+\)\s*\)\s*\)\s*
        \(CONNECT_DATA\s*=\s*\(SID\s*=\s*[^)]*\)\s*
        [(GLOBAL_NAME\s*=\s*[^)]*)]?\s*
        \)\s*\)/x;

open (FILE, "tnsnames.ora") or die $!;
while (<>) {
        if(/$pattern/){
                push @unsorted, $pattern;
        }
}
close FILE;

@unsorted = sort @unsorted;
open (FILE, "tns.log") or die $!;
while (<>) {
        if(/$pattern/) {
                push @sorted, $pattern;
        }
}
close FILE;

$x = pop @unsorted ||'' ;
$y = pop @sorted ||'' ;
while ($x || $y) {
        if($x gt $y) {
                print "missing from file1: $x \n";
                $x = pop @sorted ||'' ;
        }
        elsif ($y gt $x) {
                print "missing from file2: $y \n";
                $y = pop @sections ||'' ;
        }
        else{
        $x = pop @sorted ||'' ;
        $y = pop @sections ||'' ;
        }
