Basically you can remove script tag by using a function similar to this one:

function removeJS(filename){
 var tags = document.getElementsByTagName('script');
 for (var i = tags.length; i >= 0; i--){ //search backwards within nodelist for matching elements to remove
  if (tags[i] && tags[i].getAttribute('src') != null && tags[i].getAttribute('src').indexOf(filename) != -1)
   tags[i].parentNode.removeChild(tags[i]); //remove element by calling parentNode.removeChild()
 }
}

Note, it use filename parameter to identify target script to remove. Also please note that target script could be already executed at the time you're trying to remove it.
