Using author_sort is the default in the device interface plugin. Since your books are listed by first name on your device I'm guessing you have been filling in the author field with Last Name, First Name in the calibre library? This means by default your author sort is exactly backwards from what you expect.
Go to the tag browser, right click on authors and select manage authors
to see what is actually in your author_sort field.
By default calibre expects First Name Last Name in the author field and reverses this in the author_sort field.
Chaley has explained the fine points if, like him, you want the author and author sort fields the same.
