[Moo] font: getStyle issues IE7

[mmjaeger]

Hello
Hope somebody can help me real quick to find a solution:

I've the following code:
                arr.each(function(item){
                        //if (Browser.Engine.trident != true) {
                                item.setStyles({
                                        'font-weight'   :'bold',
                                        'font-size'             : 
item.getStyle('font-size').toInt()
*this.options.cufonSize
                                });
                        //}
                        Cufon.replace(item, { 'fontFamily': 'Bradley Hand ITC 
TT' });
                }.bind(this));

the code works fine in Firefox and Safari.

when running item.getStyle('font-size').toInt(), the following values
are returned:

Firefox: 22, 23, 23, 23, 23, 16, 16, 16 (correct)
IE: 189, 1, 1, 1, 1, 156, 156, 156 (wrong)

In my stylesheet I've got the following:
h2, .h2 {
        font-size:167%;
        font-weight:normal;
        font-style: normal;
        color:#AE0345;
}


the IE values are obviously totally wrong - is there a way around this
- any ideas are very much appreciated!

Thanks
