Take a look over this [1] blog post. It covers how to do it a little more dynamically. If you know that all of your fields can be sorted by using an integer comparison then you can set the field name as part of a static variable and then use your sObject.get method with that static var as the parameter.[1] http://blog.deadlypenguin.com/blog/2015/10/10/comparable-sorting-objects-in-salesforce/
