I’ve been working with this same code, but to filter “Coupons” by “Service Type”, where service_type is a custom post type that is part of each coupon in the form of a relationship field. The one thing that i did that made this work is to add:

$query->query_vars['meta_compare'] = 'LIKE';

in the wpse45436_posts_filter function so it should read like this:

function wpse45436_posts_filter( $query ){
    global $pagenow;
    $type = 'post';
    if (isset($_GET['post_type'])) {
        $type = $_GET['post_type'];
    }
    if ( 'sp_people' == $type && is_admin() && $pagenow=='edit.php' && isset($_GET['ADMIN_FILTER_FIELD_VALUE']) && $_GET['ADMIN_FILTER_FIELD_VALUE'] != '') {
        $query->query_vars['meta_key']     = 'sp_people_status';
        $query->query_vars['meta_value']   = $_GET['ADMIN_FILTER_FIELD_VALUE'];
        $query->query_vars['meta_compare'] = 'LIKE';
    }
}

Hope this works for you.
