The Scots weren't in Scotland in Roman times, they were (or rather, their ancestors were) cowering in Ireland, wetting their kilts in fear. After the Romans left Britain for good, the Scots still didn't start to settle in Caledonia and conquer and absorb the Picts for a century or so.
There's evidence (see the links) that the Romans established a trading presence in Ireland, btw.
Surely though, even if the Scots are treated as a later and exclusively Gaelic people, the ancient Picts (or Picti, meaning Painted Ones in Latin) in what is now Scotland were a troublesome lot for the Romans, as literary sources and the existence of Hadrian’s Wall both indicate. And it is pleasing to think of Roman contact with Ireland as including not just St. Patrick but also Roman merchants looking to buy Kerrygold in bulk at the source. And it is said that Irish traveling in the Mediterranean picked up the technique of distillation, which then became the basis for Irish whiskey.
