为了避免仅仅为了排序而进行第二次查询，您可以使用pre_user_query 挂钩以支持自定义orderby 价值

此代码仅通过设置即可在单个查询中按信誉对用户进行排序orderby 到reputation.

function wpse_296999_pre_user_query( $user_query ) {
    global $wpdb;

    $order = $user_query->query_vars[\'order\'];
    $orderby = $user_query->query_vars[\'orderby\'];

    // If orderby is \'reputation\'.
    if ( \'reputation\' === $orderby ) {
        // Join reputation table.
        $user_search->query_from .= " INNER JOIN {$wpdb->prefix}user_reputation AS reputation ON {$wpdb->users}.ID = reputation.userid"; 
        // And order by it.
        $user_search->query_orderby = " ORDER BY reputation.user_reputation_score $order";
    } 
}
add_action(\'pre_user_query\',\'wpse_27518_pre_user_query\');

if ( \'reputation\' === $orderby ) {
