That is most certainly not the reason why it does not work.

The right-hand side of the assignment is most certainly being converted to 
String as the type of the “innerHTML” IDL attribute is DOMString, therefore 
String in DOM implementations. [1]

In any event, “12” *is* _HTML_.  It is just not an HTML *element*, but then 
again nobody said it needed to be (hint: *inner*HTML).

That could be a reason why it does not work.

An (extra) identifier starting with ES 5.1 (_not_ a future reserved word as 
I thought, and as it was in ES 3, §7.5.3).  That is the primary reason why 
it does not work. [2]
