Thanks for the proposal. I included it into Wiki, but in my case the
"\WeHaveToDo" was already defined and I needed it exactly in the form
that Taco suggested (to call \OnlyStep[#1]{#2} with
\OnSteps[1-3,5]{content} in t-rsteps module).

I added it to http://contextgarden.net/Inside_ConTeXt#Processing_lists_of_values.

Taco's solution already solved my problem, but I believe it would be
nice to add some \processenumeratedlist (well, some better name should
be given!) command to ConTeXt one day. That way it would be possible
to process some commands like
    \filterpages[file.pdf][1,3,5]
also with
    \filterpages[file.pdf][1-3,5,7-11]
