Org 7.x defines the var in org-latex.el. Because it's a builtin, the custom var still displays in the 'org-latex-export group when configuring options. However, the new export logic from ox-latex.el does not define this custom var, nor does it respect the value if it is set. This is doubly confusing because it appears the var is available, but it actually unused.
I've created a patch via git format-patch which adds the custom var to ox-latex.el and makes use of it. Thanks for considering it.
