Change order of posts

Your question is not very detailed. It is hard to work out exactly what you are doing but I am assuming that you are trying to sort posts by a custom meta meta_key/meta_value. This the formula for that (annotated but basically lifted from the Codex):

 $args = array(
   'post_type' => 'your_post_type', // I don't know what this is
   'meta_key' => 'your_key', // I don't know what this is
   'orderby' => 'meta_value_num', // only for numbers; use "meta_value" for alphanumerical keys
   'order' => 'ASC',
   'meta_query' => array(
       array(
           'key' => 'your_key',
           'value' => array('your_value'), // can be more than one
           'compare' => 'IN', // see the Codex for other values
       )
   )
 );
 $query = new WP_Query($args);
