alert (app.activeDocument.selection[0].position)

will give you the top left position of the selected item - but always in points and with negativ Y-value

When I select the whole layer 

layerSM.hasSelectedArtwork = true;

If there are clipping mask in the layer, then I can't get correct position using your method..

For multiple objects that are not grouped, the script cannot simply ask for the answer.
The “position” property always returns the coordinates of the path. It does not take the stroke width into account.
Conversely, the “top” and “left” properties always return the coordinates outside the stroke width.
