I was about to say the same as Emma.
The phrase 'distinctio causa' literally means 'in order to distinguish'. The word 'Cloaks' might mean a place - there are several Cloaks around in Dumfriesshire, Kirkcudbrightshire and elsewhere, though I haven't found any in Roxburghshire. It might mean a person's name but I haven't spotted any Cloaks born in Roxburghshire in the last 500 years. Or it might simply be a garment.
My guess is that because there are a few Scott families in the area - I'm connected to one - and there are probably quite a few John Scotts, the term 'distinctio causa' is simply the clerk's posh way of saying 'nicknamed', possibly on the basis of what he habitually wears.
