Unfortunately, at a minimum, your perl is wrong. You were looking for
'!=', not '=!'. However with strings you want 'ne' instead of '!='.
The latter is for numeric comparisons.

my $a = 'Hi';

if ($a ne 'Goodbye') {
    print "Good.\n";
}

Some more things...

What version of RT are you running?

I would try a little script like this to test things out:

#!/usr/bin/perl

use strict;
use warnings;

use lib qw(
    /opt/rt4/lib
    /opt/rt4/local/lib
);

use RT -init;
my $t = RT::Ticket->new(RT->SystemUser);

$t->Load($ARGV[0]);

my $cf = $t->FirstCustomFieldValue('Solution');

if (defined $cf) {
    print "$cf\n";
}
else {
    print "__NOT_DEFINED__\n";
}

-m
