Well, you probably haven't actually found a bug.  You might have.  But
historical data predicts that you haven't.  :-)

That is your kernel version.  It looks like you are running a Linux
kernel version 2.6.27.  However the system kernel version doesn't have
very much to do with sort.  To get your sort version please ask sort
what version it is.

  sort --version

I don't know what you expect sort +n to do here.  Did you mean 'sort -n'?

Stop!  Slow down.  Breath.  You haven't described a problem yet.

Tell us *exactly* what commands you are running along with exactly
what input is going in and what output is coming out.  Please keep the
test case small.  We can't work with mail containing megabytes of
data.  Therefore reducing your problem to a very, very, very small
test case is important.

Reduce your sort problem to something very small that illustrates your
problem.  Something like this example:

  $ printf "42 uvw\n42 abc\n27 xyz\n" | sort -k 1,1n -k 2,2
  27 xyz
  42 abc
  42 uvw
