In some decks (such as the Connolly) it is not - 3 Pents is apprentice (although they have him in the Master's setting) and 8 Pents in the master builder.
The Connolly is derivative of Rider-Waite which is what I'm talking about. I'm guessing they reversed it because they couldn't figure out why the master proceeds the apprentice if you count from low to high.
