我试图在查询时显示用户，但我想按用户角色显示订单。假设我们有两个用户角色，Gold和Free。我想先显示黄金用户，然后显示自由用户。

$args = array(
                \'order\'      => \'ASC\',
                \'orderby\'    => \'display_name\',
                \'role__not_in\' => \'administrator\',
                \'posts_per_page\' => 10,
                \'meta_query\' => array(
                    \'relation\' => \'OR\',
                    array(
                        \'key\'     => \'pin_code\',
                        \'value\'   => sanitize_text_field($_GET[\'pin_code\']),
                        \'compare\' => \'LIKE\'
                    ),
                    array(
                        \'key\'     => \'city\',
                        \'value\'   => sanitize_text_field($_GET[\'pin_code\']),
                        \'compare\' => \'LIKE\'
                    ),
                    array(
                        \'key\'     => \'county\',
                        \'value\'   => sanitize_text_field($_GET[\'pin_code\']),
                        \'compare\' => \'LIKE\'
                    ),
                )
            );

            // Create the WP_User_Query object
            $wp_user_query = new WP_User_Query($args);
