It shouldn't be hard to either
- adapt the script so that it writes more lines
- write a wrapper around the script that does this in stead

The wrapper just calls the original script and duplicates the
value, thus providing a number for 'out'.  MRTG calls the wrapper.

I'm not sure about the following three statements:

- Missing lines are not a problem for earlier MRTG versions
- Missing 3rd and 4th line are not a problem for your current
  version of MRTG, but a missing 2nd line is
- Later versions of MRTG _may_ force you to return all 4 lines

So, if you're going to change the script or write a wrapper for it,
it is probably best to do it the right way and return all four lines
despite the fact that _currently_ two is enough.
