カスタム投稿タイプの年アーカイブのページング

調べたところ、どなたかのサイトで見たものを function.php に書いた下記の記述で調整できそうなんですが、

global $my_archives_post_type;
add_filter( 'getarchives_where', 'my_getarchives_where', 10, 2 );
function my_getarchives_where( $where, $r ) {
	global $my_archives_post_type;
	if ( isset($r['post_type']) ) {
		$my_archives_post_type = $r['post_type'];
		$where = str_replace( '\'post\'', '\'' . $r['post_type'] . '\'', $where );
	} else {
		$my_archives_post_type = '';
	}
	return $where;
}
add_filter( 'get_archives_link', 'my_get_archives_link' );
function my_get_archives_link( $link_html ) {
	global $my_archives_post_type;
	if ( '' != $my_archives_post_type )
	$add_link .= '?post_type=' . $my_archives_post_type;
	$link_html = preg_replace("/href=\'(.+)\'\s/","href='$1".$add_link."'",$link_html);

	return $link_html;
}

// Information年アーカイブ表示変更用（/date/xxxx/?post_type=information -> /information/date/xxxx/）
function check_custom_rules() {
    global $wp_rewrite, $add_cutom_post_rules;

    if ( ! $wp_rewrite->using_permalinks() ) { return; }
    $add_cutom_post_rules = array();
    $rule_templates = array(
        '/'                                                         => '',

    if ( $post_types ) {

                }
            }
        }

このままだと、

×　　http://ドメイン/information/date/2010/page/2/
○　　http://ドメイン/information/A/

となります。

$rule_templates = array(
        '/'                                                         => '',
        '/([0-9]{1,})/'                                             => '&p=$matches[1]',
        '/page/([0-9]{1,})/'                                        => '&paged=$matches[1]',
        '/date/([0-9]{4})/'                                         => '&year=$matches[1]',
        '/date/([0-9]{4})/page/([0-9]{1,})/'                        => '&year=$matches[1]&paged=$matches[2]',
        '/date/([0-9]{4})/([0-9]{2})/'                              => '&year=$matches[1]&monthnum=$matches[2]',
        '/date/([0-9]{4})/([0-9]{2})/page/([0-9]{1,})/'             => '&year=$matches[1]&monthnum=$matches[2]&paged=$matches[3]',

        '/date/([0-9]{4})/([0-9]{2})/([0-9]{2})/page/([0-9]{1,})/'  => '&year=$matches[1]&monthnum=$matches[2]&day=$matches[3]&paged=$matches[4]',
    );

この /date/ の前に information を付け、 /information/date/ とすると、
○　　http://ドメイン/information/date/2010/
○　　http://ドメイン/information/date/2010/page/2/
×　　http://ドメイン/information/A/
×　　http://ドメイン/information/A/page/2/
となります。
