The kilt is certainly worn on the Western Isles, although I can't say it is worn regularly as day attire.I think that also the islanders have far more important things to think about and the kilt would come way down the list of priorities. I have not ever seen the kilt worn on Orkney and I have been assured by those that live there that the kilt is not worn on Orkney. Now were they pulling my leg? They could have been, knowing who they are, but I don't think so.
