That kind of processing from the command line is just not supported (I'd have 
to be smarter than I am right now about splitting args for ipython and args 
for the upcoming script).  But you can definitely do the following:

planck[~/test]> ipython --nobanner

In [1]: cat argv.py
#!/usr/bin/env python
import sys

print 'argv:',sys.argv

In [2]: run argv.py -C somearg foo bar
argv: ['argv.py', '-C', 'somearg', 'foo', 'bar']

In practice, this should do what you want.  It's an extra step (you need to 
start ipython first and _then_ use run), but hopefully this is OK in your 
context.  Let me know if you need more details/help.
