I think if you want to blame scripting languages, you need a license plate that says "None" or "undefined".
What happened in this case was that people used the literal value "NULL" to mean "I don't know". They could have used the word "LOLCAT" and the effect would have been the same. Overuse of in-band signalling is a general design flaw not specific to any programming language. (Remember when people would whistle a 2600Hz tone to make free phone calls? Same thing as this.)
