<script type='text/javascript' src='/js/mktree.js'></script>");

Answer 2

addScript works in version 1.16 and before. In 1.17 and later you should use addHeadItem:

$wgHooks['ParserBeforeTidy'][] = 'wgAddJquery';

function wgAddJquery(&$parser, &$text) {

  global $addJqueryScripts;
  if ($addJqueryScripts === true) return true;

  $parser->mOutput->addHeadItem(
    '<script language="JavaScript" src="https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>'
  );

  $addJqueryScripts = true;

  return true;
