It should work.  Try with the following header settings:

#+header: :exports results
#+header: :results file raw
#+header: :file image.png
#+header: :fit yes
#+begin_src latex
  \begin{tikzpicture}[node distance=4cm,minimum size=2cm]
    \node[draw,fill=blue!20!white] (humanities) {Humanities};
    \node[draw,fill=blue!20!white] (tools) [right of=humanities] 
{\parbox{3cm}{Computing \\ Tools and \\ Methodologies}};
    \draw[very thick,red] (tools) edge [out=270,in=270,->] (humanities);
