You could always make an order-independant schema, then you won't have any ordering problems. Thats probably the easiest way around the problem. Other than that, you need to somehow parse your schema into a structure that you can use to know the correct place to add your new elements to. There's no feature in dom4j to do this automatically for you. You could try implementing your own special RecordElement (using your above example) such that when elements are added, they are automagically added to the correct place in the list. So adding an <Author> tag would go after the <Bookcode> but before <Price> (say).
