Is there a way to list tags order by post_meta field

$querystr = "
    SELECT DISTINCT
    -- post_meta.meta_value,
    key2.name as tag_name,key2.slug as tag_slug FROM $wpdb->posts key1
  LEFT JOIN $wpdb->term_relationships ON (key1.ID = $wpdb->term_relationships.object_id)
  LEFT JOIN $wpdb->postmeta post_meta ON (key1.ID = post_meta.post_id)
LEFT JOIN $wpdb->terms key2 ON ($wpdb->term_relationships.term_taxonomy_id = key2.term_id)
LEFT JOIN $wpdb->term_taxonomy key3 ON ($wpdb->term_relationships.term_taxonomy_id = key3.term_id)
  WHERE 1=1
  AND post_meta.meta_key = 'likes_count'
  AND post_meta.meta_value > 0
  AND (key1.post_status="publish")
  AND key3.taxonomy = 'post_tag'
 ";

 $pageposts = $wpdb->get_results($querystr, OBJECT);
print_r($pageposts);

This is the exact query for tags. I tested this and worked fine.
in below given you sample output

Array
(
    [0] => stdClass Object
        (
            [tag_name] => Tag1
            [tag_slug] => tag1
        )

    [1] => stdClass Object
        (
            [tag_name] => Tag2
            [tag_slug] => tag2
        )

)
