I am a little late, but...

If you look for changing sort order in the table view, there are two different columns: Artist (first-last order) and Artist Sort (last-first order). You can add them through right-click - Columns.

However, Artist Sort field requires attention before OrangeCD can correctly sort by it. You need to enter artists name in last, first form. To do so, right-click artist folder in the left pane and make sure "Sort name" box contains correct last-first name.

Note that the left pane always sorts artist folders by last-first name. You don't have to do anything there (except making sure that "Sort name" is correct for each artist.)
