You see it in some treatments of abstract algebra too. (Which are not unrelated to permutations in any case.) I think at least one book used in my undergrad used postfixes for function application, but I can't remember which.

Was it perhaps 'A course on Group Theory' by John S. Rose?

  Definitely not. (He may do that, I just hadn't ever heard of that book before today.) I think it was one of Isaacs, Herstein, or Artin, but I'm a bit too lazy to dig through my old books at the moment.
