Not sure why you are implementing your own compare. Instead I would add an integer sort property to your code object, where the specified order is reflected. Of your n specially sorted objects, each gets 1...n value, all the remaining being sorted elsewhere get n+1. Then you use multiple sortfields with the first sorting on the sort property, and the second on your code property.
