well you need to know java for that.
open the scrollofescape.java in the itemhandler in item_ids add your scrolls id
search for this section
case 7555:
_activeChar.teleToLocation(46934, 51467, -2977, true); // Elven Village quest scroll
break;
and add a new one like this:
case your itemid:
_activeChar.teleToLocation(your, costum, teleport, true); // your costum scrolls name
break;
