"Oriented" versus "orientated" is a which-side-of-the-pond issue. Most Brits are naturally inclined to use "orientated" where Americans would use "oriented" (which, to them, would mean something along the lines of "lustrous" or "pearlescent" but with an archaic flavour). Some are able to swallow the bile and use a word that feels just wrong when writing for an international audience, but not all.
