Yes, of course.  I don't think any of us meant these ideas seriously.
Was this the only objection you had?

In fact, at least FreeBSD sort -n handles the numbers quite happily.
I've tried it with 4.4BSD sort, which with a little coaxing builds
under FreeBSD.  It doesn't: it apparently sees the , as a delimiter.

The real question is whether a comma is a valid character in an
integer.  There are arguments that it should be.
