您可以尝试使用元查询筛选结果，然后将orderby添加到订单结果中。下面的参数应该有效

$args = array(
 \'post_type\' => array(\'post\', \'video\'),
 \'meta_key\' => \'pp_like_count\',
 \'orderby\'  => \'meta_value_num\',
 "meta_query" => array(            
        array(
            "key" => "pp_lang",
            "value" => "english",
            "type" => "CHAR",
            "compare" => "="
        ),
    ),                 
);
