#+begin_dot out.pdf -Tpdf
digraph test {

can be used with the current setup to go straight from dot -> PDF.
Since you would rather go to EPS as an intermediary step, then I would
recommend defining a new block type which can handle this two-stage
process. There are instructions in org-exp-blocks.el, and I would
recommend using `org-export-blocks-format-dot' in
contrib/lisp/org-exp-blocks.el as your starting point. It should be
possible to achieve the result your want with only one or two lines of
new elisp probably inserted right after the following line
(shell-command (concat "dot " data-file " " args " -o " out-file))
