Well, for me orientation / rotation make sense, as I feel it, "orientation" means like a sort of immanent concept, it's one of the attribute of a node. Meanwhile "rotation" refers to a change in a state, it implies some kind of transformation to the initial node attributes. So to me it make sense ^^.
For the place modifier I don't know, once I understood it's use it does not bothered me, but transform can be nice also ^^
