I don't know how Carsten will address this, but it seems that the running
of the org-export-preprocess-hook is done too late for your purposes (from
inside org-export-preprocess-string and inside a

       (with-current-buffer (get-buffer-create " org-mode-tmp")
          ...

construct, where there is no buffer file name).

Can you run org-update-all-dblocks by hand before doing the export?  That should
update the org file and the export should then have all the right
information, no? If so, you can even automate the process by advising
org-export, so that org-update-all-dblocks is run before org-export
proper is called. [1]

HTH,
Nick
