I've spent some time looking at this.

A couple of things are happening.  Back in the time of 7.8.03 and
7.8.04, the org-babel-execute:sh call happened in such a context that
all external function calls would take place on the remote machine if
the :dir header specified a tramp path to a remote machine.  This is
true both before and after my 5cb80c7e5b9bca commit.

However this has changed between then and now, meaning that reverting
the 5cb80c7e5b9bca commit now will not solve this problem.  In the
current branch there is no change of context s.t. external calls made by
the org-babel-execute:* functions happen by default on the remote
machine.  I think this is the real problem.  Perhaps it would be
possible to git bisect with another language like perl?

Sorry I'm not more help here, the remote-execution magic was mainly
implemented by Dan Davison.
