How to order posts in wp_query by the user role (2 roles in array)

Question

Its possible with an ugly custom query but to save your self a lot of time an easier solution would be to add a custom field to each post with the user role , then your query would be much smoother for example say you have a custom field named `u_role’ then your query should look like this:

$news = new WP_Query( array(
    'author' => implode( ',', $friend_ids ),
    'post_type' => 'news', 
    'paged' => get_query_var('paged'),
    'meta_key' => 'u_role',
    'orderby' => 'meta_value', 
    'order' => 'DESC') );
