try something like:

  (nth 3 (split-string (shell-command-to-string "grep --version")))

the 3, being a hardcoded constant (that is neither 0 nor 1 ;-), should
be a hint that there is a code enhancement opportunity here...

alternatively, avoid the pitfalls of inferring/assigning meaning to
version numbers and do some kind of test on the program in question,
directly.
