Find post of author with meta_key - Wordpress

Question

This's my query:

$list = query_posts(array(
    'post_type' => 'post',
    'author' => $current_user->ID,
    'category__in' => array(11),
));

It ok, but when I change it to:

$list = query_posts(array(
    'post_type' => 'post',
    'author' => $current_user->ID,
    'category__in' => array(11),
    'meta_key' => 'author_alias_id',
    'meta_value' => '1'
));

The result is empty.

Somebody can help me?
