In the org-html-mathjax-options variable description , say #+MATHJAX: path:"http://url/MATHjax.js" can be ued to set the variable 

org-html-mathjax-options to  `((path "http://url/MATHjax.js")  but it not work. 

Set the variable in .emacs is OK, but in Org file, 

+MATHJAX: path: "http://somepath/Mathjax.js" 

is not work.
