There is something close that specifies exactly this behavior:

<http://www.w3.org/TR/2014/CR-html5-20140204/scripting-1.html#the-script-element>

I think it is only logical that the script element resource would not be 
parsed before it is inserted because a client-side script may depend on 
symbols defined in other scripts that may need to be included dynamically as 
well.

However, it should be noted that loading script elements this way is 
asynchronous: you cannot assume that the symbols in the loaded script are 
immediately available afterwards.  It is therefore good that HTML5 CR also 
specifies events like “beforescriptexecute”, “afterscriptexecute” and, most 
notably, “load”, for the “script” element.  It would appear that, finally, 
there is going to be a standards-compliant way to load script resources 
dynamically without resorting to hacks and XHR.
