The text part in rule 6 is supposed to be the definition of the score:

The score for each hole is the total number of bytes you need (smaller is better). If your program is more than one line, you must count the newlines in between as one byte each. The #! line is not counted. If you use options on the #! line, the options themselves are counted, including the leading whitespace, the - and any trailing whitespace (but not the newline)
