There are none in Prototype.js simply because it is a rather small and  
low level library (I'm one of its core developers, btw). Libraries  
that use, say, "global eval" abstraction and/or dependency management  
(for scripts and styles) such as YUI obviously use HEAD more often  
(which your numbers confirm).
