Exclude posts by post meta value

$args = array(
   'meta_key'   => 'home_post_id',
   'orderby'    => 'meta_value_num',
   'order'      => 'DESC',
   'meta_query' => array(
       array(
           'key'     => 'home_post_id',
           'value'   => 0,
           'compare' => '>',
           'type'    => 'numeric',
       )
   )
);
query_posts($args);

Something like this should work but I haven’t tested it .)
Let me know if it works..
