For reference:
I got it to work by adapting the snippet from Bruno Tavernier[1]:
#+begin_src emacs-lisp
(defun my-auto-tex-cmd (backend)
"When exporting from .org with latex,
automatically run latex, pdflatex, or xelatex as appropriate,
using latexmk."
(let ((texcmd))
(setq texcmd "latexmk -pdf %f")
(if (string-match "LATEX_CMD: pdflatex" (buffer-string))
(setq texcmd "latexmk -pdflatex=pdflatex -pdf %f"))
(if (string-match "LATEX_CMD: pdflatex-shell-escape" (buffer-string))
(setq texcmd "latexmk -pdflatex=pdflatex --shell-escape -pdf %f"))
(if (string-match "LATEX_CMD: xelatex" (buffer-string))
(setq texcmd "latexmk -pdflatex=xelatex -pdf %f"))
(setq org-latex-pdf-process (list texcmd))))
(add-hook 'org-export-before-parsing-hook 'my-auto-tex-cmd)
#+end_src
One thing that tripped me up initially was the requirement for the function to
accept exactly one argument (unused in this case).
