Nobody (yet) has mentioned how your code could have been written to fix the mistake, so I'll do it ;) 
for my $record (@$records) {
    my $editor;
    print $lbr, "Record: $record->{'zone_record_id'}";

    if ( @{$record->{services}} == 0 ) {
        $editor = 'plain edit';
    }
    elsif ( $record->{services}[0]{class} =~ /Primary|Secondary/ ) {
        $editor = 'no editor';
    }
    else {
        $editor = 'service edit';
    }
    print $editor;
}
