magento - 税收不适用于以编程方式创建的订单

Question

我以编程方式创建了一个订单。创建工作正常，但如果我在admin-interface中检查订单，那么订单没有设置税。

产品本身已征税。我是否必须以某种方式在订单创建中写税？

这是我用来生成订单的类：

class OrderGenerator
{
    const CUSTOMER_RANDOM = null;

    protected $_shippingMethod = 'freeshipping_freeshipping';
    protected $_paymentMethod = 'cashondelivery';
    protected $_deliveryDate = null;
    protected $_baseOrder = null;

    protected $_customer = self::CUSTOMER_RANDOM;

    protected $_subTotal = 0;
    protected $_order;
    protected $_storeId;

    public function setShippingMethod($methodName)
    {
        $this->_shippingMethod = $methodName;
    }

    public function setPaymentMethod($methodName)
    {
        $this->_paymentMethod = $methodName;
    }
    public function setDeliveryDate($date)
    {
        $this->_deliveryDate = $date;
    }
    public function setBaseOrder($order)
    {
        $this->_baseOrder = $order;
    }

    public function setCustomer($customer)
    {
        if ($customer instanceof Mage_Customer_Model_Customer){
            $this->_customer = $customer;
        }
        if (is_numeric($customer)){
            $this->_customer = Mage::getModel('customer/customer')->load($customer);
        }
        else if ($customer === self::CUSTOMER_RANDOM){
            $customers = Mage::getResourceModel('customer/customer_collection');

            $customers
                ->getSelect()

        }
    }

}

我使用的课程如下：

 // $validityDate is a date object
 // $order is a valid $order object
 // $productCollection is a collection of items like { product: 23, qty: 1 }
 foreach ($orderProductArray as $validityDate => $productCollection) {
      $orderGenerator = new OrderGenerator();
      $orderGenerator->setDeliveryDate($validityDate);
      $orderGenerator->setBaseOrder($order);
      $orderGenerator->createOrder($productCollection);
 }
