JS CS3 copy, paste and transform

Question

I have a script that allows the user to select objects on a page (in this case text frames) and create a new page user defined and then paste the selection on the page and make it fit the page size.
I'm having a slight problem where the text frames in the group are not showing the text (get text overflow) after the resize. If I comment out the myGroup.geometricBounds = [0,0,38,38]; line in the script below and manually resize the group to the document height and width (38,38) the text frames in the group are all ok.
var myNewGroup = new Array;
for (i=app.selection.length-1; i>=0; i--) {
myNewGroup.push (app.selection[i]);
var myGroup = app.activeDocument.groups.add(myNewGroup);
myGroup.move(Array(0,0) )
myGroup.geometricBounds = [0,0,38,38];
If anyone has any suggetions it would be greatly appreciated.
John.

This seems to be working. I went with the transform() in the end. If anyone has a better way please let  me know.
var myNewGroup = new Array;
     //make group
for (i=app.selection.length-1; i>=0; i--) {
    myNewGroup.push (app.selection[i]);
  var myGroup = app.activeDocument.groups.add(myNewGroup);
  myGroup.move(Array(0,0) )
       //get size of group
  var mySelSize = myGroup.geometricBounds;
         //get size of document
    var myDocHSize = app.activeDocument.documentPreferences.pageHeight;
    var myDocWSize = app.activeDocument.documentPreferences.pageWidth;
         //get scale value
    var myScalH = myDocHSize/mySelSize[2];
    var myScalW = myDocWSize/mySelSize[3];
         //apply transform scale
    var myScaleMatrix = app.transformationMatrices.add({horizontalScaleFactor:myScalW, verticalScaleFactor:myScalH});
    myGroup.transform(CoordinateSpaces.pasteboardCoordinates,AnchorPoint.topLeftAnchor, myScaleMatrix);
