I can’t reproduce this on org master.

I believe you can add a name to the results, and use that:

,----
| #+name: input
| #+BEGIN_SRC sh :results output :cache yes
| echo "3"
| #+END_SRC
| 
| #+name: input-results
| #+RESULTS[f69ecd305ebd448fc39b05809d214261a777c6bc]: input
| : 3
| 
| #+BEGIN_SRC R :var a=input-results
| a
| #+END_SRC
| 
| #+RESULTS:
| : 3
`----


Hope this helps,
