See the attached tentative patch.
Thanks for prompt reaction.

Since directory name already contains "org", it may be shortened to just
"tex"
(texfile (concat texfilebase ".tex"))
I would use `make-temp-file' to create TEXFILE and would derive
TEXFILEBASE from it. In general it is safer.
To create directory I expect a call of a function similar to the
following one. Perhaps it exists already somewhere.
(defun org-ensure-tmp-dir (dir-symbol prefix)
(let ((dir (symbol-value dir-symbol)))
;; Temporary directory has not been cleaned.
(or (and dir (file-directory-p dir) dir)
(setf (symbol-value dir-symbol)
(make-temp-file (or prefix "orgtmp-") 'dir)))))
(defvar org-tex-tmpdir nil)
Usage example: (org-ensure-tmp-dir 'org-tex-tmpdir "orgtex-")
Fixed directory name is not friendly for multi-user systems and
predictable name in /tmp might be a source of security issues.
