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="">  "\
\\int_0^2 e^x dx
\"
#+END_SRC

works better for latex. I guess that is always going to be some kind of limitation.

Slight modification : caption in emacs-lisp (to avoid sh blocks) : see the enclosed archive (necessary to avoid anti-spam blocking by my ISP).

Mixed results (see enclosed archive):

- ODT exports : I get a captioned block containing the equation, correctly referenced.

- HTML : I get the equation (via MathML/Mathjax), no caption and a reference to nothing visible.

- PDF via LaTeX : I get the math and an undefined reference (??).

- Docx from ODT : mangled math, unrelated caption, reference to nothing.

There is a nice idea, but it is still perfectible. I'm afraid that filering by exporter is still necessary...

Thank you again !
