The word as it's known and used today and millenia past means any person or persons who can cast or use magic. It does mean priest, cleric, sorcerer, wizard, witchdoctor, witch, etc.. etc...
I've always used it to mean the same thing in my DnD games but that is personal. A lot of people don't even know that the term magus or magi can cover the divine aspects of spellcraft.
Anyways, we all use it as we see fit in our DnD games.
As for the robe, I see no need too change it or anything as it is. How do you know that the robe wasn't created by a priest of Boccob who was also a decent level wizard or sor also. There is no history to the item itself in the DMG. Remember, this is 3e, not 1e or 2e.
