最终通过以下代码解决了此问题：

<ol class="commentlist">
        <?php $comments = array_reverse($comments, true); ?>
            <?php
                /* Loop through and list the comments. Tell wp_list_comments()
                 * to use twentyten_comment() to format the comments.
                 * If you want to overload this in a child theme then you can
                 * define twentyten_comment() and that will be used instead.
                 * See twentyten_comment() in twentyten/functions.php for more.
                 */
                wp_list_comments( array( \'callback\' => \'twentyten_comment\',\'status\' => \'approve&number=5\',\'order\' => \'asc\' ) );
            ?>
        </ol>
