After performing a search on Vista you should see a column labeled Size. If you click on that you can change the sorting from smallest to largest and vice versa. Vista has a new feature that lets you stack files by the column value. Hover over the Size column and you'll see a dropdown arrow to the right. Clicking on that will show you the new stacking and grouping options.
