Here's what I use.

userHoriz = app.documents[0].viewPreferences.horizontalMeasurementUnits;
userVert = app.documents[0].viewPreferences.verticalMeasurementUnits;
app.documents[0].viewPreferences.horizontalMeasurementUnits = MeasurementUnits.points;
app.documents[0].viewPreferences.verticalMeasurementUnits = MeasurementUnits.points;
myDoc = app.activeDocument;
myFrame = app.selection[0];
myIndx = myFrame.characters[-1].index;
myColumns = myFrame.textFramePreferences.textColumnCount;
userZP = myDoc.zeroPoint;
myDoc.zeroPoint = [myFrame.geometricBounds[1],myFrame.geometricBounds[0]];
myJust = myFrame.textFramePreferences.verticalJustification;
myBounds = myFrame.geometricBounds;
origHeight = myBounds[2] - myBounds[0];
myFrame.textFramePreferences.verticalJustification = VerticalJustification.topAlign;
myLength = 0;
for (var j=0; myFrame.textColumns.length > j; j++) {
 myLength = myLength + myFrame.textColumns[j].lines[-1].baseline;
}

myNewBot = (myLength)/(myColumns) + 8;
 myBounds[2] = myNewBot
 myFrame.geometricBounds = myBounds;

while (myFrame.characters[-1].index == myIndx) {
  myBounds = myFrame.geometricBounds;
  myBounds[2] = myBounds[2] - 3;
  myFrame.geometricBounds = myBounds;
 }
 while (myFrame.characters[-1].index < myIndx) { myBounds = myFrame.geometricBounds;  myBounds[2] = myBounds[2] + 1; myFrame.geometricBounds = myBounds; }

myFrame.textFramePreferences.verticalJustification = myJust;
 app.documents[0].viewPreferences.horizontalMeasurementUnits = userHoriz
 app.documents[0].viewPreferences.verticalMeasurementUnits = userVert
myDoc.zeroPoint = [0,0];
myDoc.zeroPoint = userZP;
