Best guess is that you forgot to print the Content-Type header before the loop you have shown us. Working SSCCE:

#!/usr/bin/env perl
use strict;
use warnings;

print "Content-type: text/plain\n\n";

my %folderhash2 = (
    '1005' => 'SG',
    '1007' => 'NA',
    '1010' => 'Global',
    '0'    => 'None',
    '1006' => 'Link',
); 

foreach my $folderMap2 (sort keys %folderhash2) {
    printf "%-8s %s\n", $folderMap2, $folderhash2{$folderMap2};
}
