Hi.
Did you mean to start your function when you change the status of the order to delivered in the administration?

public function hookActionOrderStatusPostUpdate($params)
{
    $idOrder = $params['id_order']; // ID Order
    $oldOs = $params['oldOrderStatus']; // previous Order status
    $newOs = $params['newOrderStatus']; // current ID Order status
    $myOsShipped = 4; // Shipped
    $myOsDelivered = 5; // Delivered


    if ($newOs == $myOsShipped) {
        // your function after change state to shipped
    }

    if ($newOs == $myOsDelivered) {
        // your function after change state to delivered
    }
}
