To achieve this:

Use this code:

add_filter( 'custom_menu_order', 'wpse_48933_submenu_order' );

function wpse_48933_submenu_order( $menu_ord ) 
{
    global $submenu;

    // Enable the next line to inspect the $submenu values
    // echo '<pre>'.print_r($submenu,true).'</pre>';

    $arr = array();
    $arr[] = $submenu['edit.php?post_type=page'][10];
    $arr[] = $submenu['edit.php?post_type=page'][5];
    $submenu['edit.php?post_type=page'] = $arr;

    return $menu_ord;
}
