That's the historical pre-POSIX notation.  I believe the equivalent
POSIX notation is:

  sort -t^ -k12,11 -k3,7

... except that I haven't tested that, and have no idea what it might
mean for POS1 (11) to be greater than POS2 (10) - is this real code or
just an example?

You might also consider using C++'s native sorting facilities rather
than forking an external process.
