How a script can know if it has been called with the -i commandlineoption?

True. - I was under the impression that sys.argv has all the stuff in it,
but it just ain't so - I made a file called junk.py containing two lines:

import sys
print sys.argv

and sys.argv just has junk.py in it, for both styles of command line.

I also noticed that if you do the following:

python junk.py -i

then the interpreter is not interactive.  I was also not aware that 
the options had positional dependency.

you could do a work around by calling it like this:

python -i junk.py -i

then sys.argv has the extra -i...

or better, insist on being told in both cases with say -i and -n at the end.

it does not answer the real question, though, as someone could lie to you.
