Why use regex when there is a module to do this for you? 
#!/usr/bin/perl

use strict;
use warnings;
use Text::CSV;

my $csv = Text::CSV->new ({ sep_char => '|' });

while (<DATA>){
    my $line = $_;
    chomp;
    next if (/Order/);
    print ("string $_ \n");
    $_ =~ s/\"//g;
    my @array = split /\|/ ;
    print("order $array[0] , wrong sometimes $array[3]\n");
    my $status  = $csv->parse($line);
    my @columns = $csv->fields();
    print("order $columns[0] , right  $columns[3]\n\n");
}

__DATA__
"129822"|"Custom Currency"|"Living the | Dream"|"400"

The questions isn't is someone likely to put that pipe dream in there, the question is if you should ever have to care if they do!
