But seriously, Folks, I think it's fairly clear that Howard is using “real” in the sense of physical reality, as Peirce did when he wrote “real world”, and as all of us do when that's what we mean. But I can assure you that mathematicians as a rule, including Peirce, regard mathematical objects as “having properties”, which makes them “real” according to the technical Scholastic definition of “real” that Peirce always uses and often mentions when he's being precise.
