Routing problem

Hello.

I'm setup multiple app and set this routes:

 // public route pattern
$router->add("/:module/:controller/:action/:params", array(
    "module" => 1,
    "controller" => 2,
    "action" => 3,
    "params" => 4
));

// custom route
$router->add("/people_zone/people/register-new-people", array(
    "module" => "people_zone",
    "controller" => "People",
    "action" => "registerForm"
));

$router->notFound(array(
    "controller" => "Error",
    "action" => "error404"
));

I want to implement this senario: have a public route pattern alongside custom routes, if route not match with public pattern the look for custom routes, but while i'm specified public pattern, custom routes are ignored.

In above case when i enter localhost/mybaseuri/people_zone/people/register-new-people the app say: "register-new-people action not found"
