Like I said, it depends on the load order. Basically, the way your DLCs (and mods) are arranged, which you can view and change in the "data files" section of the launcher.

In my game, I have a HD texture pack as my first DLC (in the list), then Dawnguard at 02, Dragonborn at 03 and Hearthfire at 04.
