Apparently the item order corresponds with the list I posted in a previous thread:
However, in the above list, the weapons are listed first followed by armor sets, spells, rings, consumables, gestures and boss souls. Also, for some reason, all the armor sets and weapons from the Network test are listed at the very end (they were probably changed in final version of the game, but are still present in the game files). Notice that in the image posted by TC the armor and weapon categories end with items from the Network test.
I remember being disappointed that there wasn't a more pristine version the the Balder Knight armor in Dark Souls. It looks like this might not be an issue in Dark Souls 2, because it looks like there are restored versions of most of the tattered armor.
