Displaying all items which have been backordered within an order?

Question

Using Magento EE 1.9, I've enabled backorders, but there's no way to see if an order contains backordered items in the Sales/Orders grid view.

How would I check if an item was backordered or not after an order has been placed?

(Code-based solutions are fine.)

Something like this maybe:

    $items = array();
    $order = Mage::getModel('sales/order')->load($orderId);
    $orderItems = $order->getAllVisibleItems();

    foreach ($orderItems as $orderItem) {
        $sumBackordered = 0;
        $children = array();

        if ($orderItem->getHasChildren()) {
            foreach ($orderItem->getChildrenItems() as $childItem) {
                $sumBackordered += (float)$childItem->getQtyBackordered();
                $children[] = array(
                    'name'              => $childItem->getName(),
                    'qty_backordered'   => (float)$childItem->getQtyBackordered()
                );
            }
        }

        $items[] = array(
            'name'              => $orderItem->getName(),
            'qty_backordered'   => $orderItem->getHasChildren() ? $sumBackordered : (float)$orderItem->getQtyBackordered(),
            'children'          => $orderItem->getHasChildren() ? $children : null
        );
    }

    Zend_Debug::dump($items);
