Incidentally, haven't the Scott and Buccleuch titles passed through the female line, Ann(e?) Scott being the sole heiress and being married off to James, son of Charles II and Lucy Walters, who adopted the name of James Scott?

Whittakers has a list of family names of peers with the relevant title, and the Duke appears under M for MDS, not S.
Yes, Anne Scott (maybe Anna) succeeded to the title Countess of Buccleuch on her sister's death in 1661. When she married James, Duke of Monmouth (a.k.a. James Crofts or James Fitzroy, illegitimate but recognized son of Charles II and his mistress Lucy Walters) in 1663, they were created the Duke and Duchess of Buccleuch. He took the surname Scott when they married. She was created Duchess in her own right (largely due to her wealth and property holdings), and was thus unaffected by James' attainder in 1685.

From what I understand of titles, etc., Buccleuch is a "Scott title", as you put it. 'Buccleuch' is simply the way one refers to a Duke (by his title), just as one would refer to 'Montrose' or 'Argyll'. It's not the family name (though some members of Clan Scott do have the surname Buccleuch or variants - Buckalew, etc.).

'Scott of Buccleuch' is the senior line of Clan Scott. The cadet branches are (from the Clan Scott Society FAQ): 'Scotts of Harden, Scotts of Balwearie, Scotts of Raeburn, Scotts of Thirlestane, Scotts of Tynedale, Scotts of Ancrum, Scotts of Synton, and Scotts of Scotstarvet, Goudilands, Gala, Melby, Malleny, Dunninald, and many more'. BTW, Lord Polwarth is a Scott of Harden, so not all "Scott titles" belong to Scott of Buccleuch.

Again, from what I've read in the Clan Scott Society newsletter, the late 9th Duke preferred the surname Scott to the full 'MDS', and that is what the family now use, though on their legal paperwork they may still have the 'MDS' name.
