You could try to use the DOM Mutation events:

DOMAttrModified
DOMAttributeNameChanged
DOMCharacterDataModified
DOMElementNameChanged
DOMNodeInserted
DOMNodeInsertedIntoDocument
DOMNodeRemoved
DOMNodeRemovedFromDocument
DOMSubtreeModified

like so:

document.head.addEventListener ('DOMNodeInserted', function(ev) {
   if (ev.target.tagName == 'SCRIPT') {
       ev.target.parentNode.removeChild(ev.target);
   }
}, false);

Also you can try the new way of doing this through MutationObserver
