Brilliant!

# Look for the first negative number (if any)
for i,arg in enumerate(sys.argv[1:]):
    # stop if a non-argument is detected
    if arg[0] != "-": break
    # if a valid number is found insert a "--" string before it which
    # explicitly flags to getopt the end of options
    try:
        f = float(arg)
        sys.argv.insert(i+1,"--")
        break;
    except ValueError:
        pass
