Actually... I don't know why that (read result) is there at all: result
is a string representation of the result that the scheme interpreter
returned. It does not make any sense to me that we try to read that and
make it into an elisp object: we should just return the string itself.

With that change (see attached patch) on more-or-less current master
(the exact version is Org-mode version 8.3.1 (release_8.3.1-236-g14f5f6
@ /home/nick/src/emacs/org/org-mode/lisp/), I can evaluate everything
that you sent out without any error (see attached file "scheme.org"
which includes evaluation results).

N.B. this is with guile: I have not tried chicken, MIT Scheme or any
other scheme implementation.
