title: Adding a new attribute to order in magento
body: <p>I want to add an attribute to order that will not be visible to customer. I just want to use it in database and storing a specific value for each order. I want to print order according to this value. So how can i add an order attribute in magento. The attribute is just like status of order. Further on if i want to show that attribute in admin/sales/orders how can i do that?</p>
