Hi Nigel,
Org-mode gnuplot code blocks do make use of user variables [1] for
passing arguments into gnuplot. I believe that this feature may only be
available in later versions of gnuplot. I'm using gnuplot 4.4 locally
and I've had no problems using gnuplot from Org-mode code blocks which I
do most every day.
the syntax for defining variables is fairly simple, try the following
directly in the gnuplot terminal, if your gnuplot does have variable
support it should graph a straight line of y=10
#+begin_src gnuplot
a=10
plot a
#+end_src
