How correctly update status for order?

i have this code, but it's not working for me

public function salesOrderSaveAfter($event){

        //check for fires twice 
            $order = $event->getOrder();
            $orderIncrementId = $order->getIncrementId();

            Mage::log('i here');
            foreach ($order->getAllVisibleItems() as $item){
                $oldQty = (int)$item->getProduct()->getStockItem()->getQty();
                $qtyOrdered = (int)$item->getQtyOrdered();

                $differenceQty = $oldQty - $qtyOrdered;

                //increase the price by 25%
                if($oldQty > 0 AND $differenceQty <= 0 ){
                    $product_model = Mage::getModel('catalog/product')->load($item->getProductId());
                    $price = $product_model->getPrice();
                    $newPrice = $price + (($price * 25) / 100);

                    //update status for order
                    $order = Mage::getModel('sales/order')->loadByIncrementId($orderIncrementId);
                    $state = 'new';
                    $status = 'backorder_status';
                    $isCustomerNotified = true;
                    $order->setState($state, $status, $isCustomerNotified);

$order->setState($state, $status, $isCustomerNotified); looks like a problem.

To set multiple values on an object, they have to be specified separately, as in $order->setState($state)->setStatus($status).

However, I think what you actually want to do is create a new sales/order_status_history object. This is the "Magento" way, that will ensure that all the corresponding boxes are checked.

app/code/core/Mage/Sales/Model/Order.php includes the addStatusHistoryComment method, which returns a Mage_Sales_Model_Order_Status_History object that can be further modified by setting a value for isCustomerNotified.

See the addCommentAction method in app/code/core/Mage/Adminhtml/controllers/Sales/OrderController.php for an example:

public function addCommentAction()
        if ($order = $this->_initOrder()) {
            try {
                $response = false;
                $data = $this->getRequest()->getPost('history');
                $notify = isset($data['is_customer_notified']) ? $data['is_customer_notified'] : false;
                $visible = isset($data['is_visible_on_front']) ? $data['is_visible_on_front'] : false;

                $order->addStatusHistoryComment($data['comment'], $data['status'])
. . .
