Title: Update library/Zend/View/Helper/HeadScript.php

What this does:
This fix would result in that the 3rd param is the conditional string

Reason:
I would like to see the same pattern used for this method as for HeadLink::_call (eg. appendStylesheet, offsetSetStylesheet, prependStylesheet and setStylesheet)
