I think some of the thirteenth-century monarchs used 'rex Scotiae' on occasion, almost certainly definitely King John [Balliol] though his title to the throne rested on a distinct basis to his predecessors and successors. It's all in A.A.M. Duncan, The Kingdom of the Scots, which is well worth reading, though very historically contentious.
