TextItem.size is wrong after transform (CS 6)

Question

Hey, i've a export script for Photoshop, which creates a XML file.
On field in this XML is the font size for each text layer. But the .size value is wrong when we transform the text layer.
Example and steps to reproduce:
create a text layer
set font size 6pt (font family doesn't matter)
TextItem.size will export "6 pt"
transform the text - make it larger
Photoshop shows for example "12 pt" as the font size
TextItem.size still exports "6 pt"
Is there any way to get the correct font size?
When transforming text, you will get a value like "11.9999 pt" (you mostly don't get a round number).
But when you try to set the font size to 12 pt manually, TextItem.size still exports the old value.
The exporter works great in CS 3, the font sizes are correct. But in CS 6 its wrong.
Is this a PS bug maybe?

Here is an example of getting all text layer names and font sizes...
main();
function main(){
if(!documents.length) return;
var txtLayers = getNamesPlusIDs();
var txtSize = new Array();
for(var a in txtLayers){
    txtSize.push([[txtLayers[a][1].toString()],[getTextSize(Number(txtLayers[a][0]))]]);
alert(txtSize.join('\n'));
function getNamesPlusIDs(){
   var ref = new ActionReference();
   ref.putEnumerated( charIDToTypeID('Dcmn'), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
   var count = executeActionGet(ref).getInteger(charIDToTypeID('NmbL')) +1;
   var Names=[];
try{
    activeDocument.backgroundLayer;
var i = 0; }catch(e){ var i = 1; };
   for(i;i<count;i++){
       if(i == 0) continue;
        ref = new ActionReference();
        ref.putIndex( charIDToTypeID( 'Lyr ' ), i );
        var desc = executeActionGet(ref);
        var layerName = desc.getString(charIDToTypeID( 'Nm  ' ));
        var Id = desc.getInteger(stringIDToTypeID( 'layerID' ));
        if(layerName.match(/^<\/Layer group/) ) continue;
        var layerType = typeIDToStringID(desc.getEnumerationValue( stringIDToTypeID( 'layerSection' )));
        var isLayerSet =( layerType == 'layerSectionContent') ? false:true;
        if(desc.hasKey(stringIDToTypeID('textKey'))) Names.push([[Id],[layerName]]);
return Names;
function getTextSize(ID){
var ref = new ActionReference();
ref.putIdentifier(charIDToTypeID('Lyr '), ID);
var desc = executeActionGet(ref).getObjectValue(stringIDToTypeID('textKey'));
var textSize =  desc.getList(stringIDToTypeID('textStyleRange')).getObjectValue(0).getObjectValue(stringIDToTypeID('textStyle')).getDouble (stringIDToTypeID('size'));
if (desc.hasKey(stringIDToTypeID('transform'))) {
            var mFactor = desc.getObjectValue(stringIDToTypeID('transform')).getUnitDoubleValue (stringIDToTypeID("yy") );
    textSize = (textSize* mFactor).toFixed(2);
return Number(textSize).toFixed(2);
