Custom Page Order instead of Alphabetical

Create a custom navigation menu and order the pages in wp-admin/nav-menus.php. You shouldn’t mess around with wp_list_pages() anymore.

To get a Home link into the list of available pages add the following code to your theme’s functions.php:

add_filter( 'wp_page_menu_args', 'add_home_link_to_nav_menu_editor' );
function add_home_link_to_nav_menu_editor( $args )
{
    $args['show_home'] = TRUE;
    return $args;
}
