Instead of doing an unset (I'm not sure how you would do that), why not just set it to the postcount you want it to stay at?

PHP Code:

if ($this->fetch_field('userid') == 36)
{
if($this->fetch_field('posts') >= 666)
{
$this->set('posts', 666);
}
} 


Although, looking more into it there, it doesn't look like the posts are actually saved there. It looks like it is passed back in the $userinfo array. So, I think you may want to do something more along these lines (again, not tested, play with it on a test site):

PHP Code:

if ($this->fetch_field('userid') == 36)
{
if($this->fetch_field('posts') >= 666)
{
$posts = 666;
            $userinfo = array(
                'userid' => $userid, // we need an userid for is_member_of's cache routine
                'posts' => $posts
            );
}
}
