So... what the conclusion...
Well, IMO, it really was unimportant, so even in fact the Orkney-Shetland were only
pawned to the Scottish king for 52.000 unpaid florins of dowry, they never were get out of pawn (so Denmark still could buy them, yeah?

)… But you can see these issues were raised even 100 years later - during the negotiation over the marriage contract between James VI and Princess Anna of Denmark in 1589. But the Danes even did not care to put this matter to the treaty once again.
I believe that it will be better just to unite Orkney-Shetlands with Highlands, but to put +1 (or 2) tax base to Bergenhus and then to transfer it in 1468-1470 to Scotland (there were two treaties in fact as Shetlands were given two years later for the rest 2.000 florins) to Scotland. On the contrary it is possible to make alternative event, where Denmark (I think that it should be triggered first to Danish player or AI and then to Norway and Scotland) could pay the full sum or to “transfer” the islands to Scotland
