This works as expected in LaTeX for me with org-ref (you could probably use
raw latex if you wanted):

#+caption: The first source block. label:src-1
#+BEGIN_SRC ipython
print('Hello world')
#+END_SRC


Later we refer to the code in Listing ref:src-1 or ref:src-2. That is
different than Figure ref:fig-1.

#+caption: My figure. label:fig-1
[[./test.png]]


#+caption: The first source block. label:src-2
#+BEGIN_SRC ipython
print('Hello world')
#+END_SRC

The downside is that for html the src-block links are not numbered. I don't
know how easy that would be to fix in the export functions.
