I think that you will find that Suckling/ScotAir has always had trouble staffing the Scottish bases. Dundee in particular. It is probably for this reason that there may be a bias in favour of Scots pilots, although it is possible that there might be a Souter/Gloag bias somewhere. Dedication to relocate to Scotland and perhaps show true commitment by buying a house up there would no doubt go a long way to swinging the balance in your favour.
God luck then!
