Firstly ensure the Nokia Maps library loads first by declaring it first i.e.:
Secondly comment out the following in the mootools-core-1.4.5-full-compat.js file:
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=7; IE=EmulateIE9" />
<title>Premiership: Nokia Maps with Mootools</title>
The map will then work, I'm not sure of the effect on the Mootools codebase since this means the system is using the Nokia Maps version instead.
var i = this.length, clone = new Array(i);
while (i--) clone[i] = cloneOf(this[i]);
