I am not sure you have the best math example, isn't the syntax \[\] for
unnumbered equations in latex? What would it even ref? In the export, you
can see that there is no label in the tex at least.
#+BEGIN_SRC emacs-lisp :exports both :results value drawer :post
caption(name="eq-integral", caption="This is an equation.", data=*this*)
"\\begin{equation}
\\int_0^2 e^x dx
\\end{equation}"
#+END_SRC
works better for latex. I guess that is always going to be some kind of
limitation.
