Sort Finder columns reversed I can't get this reversed thing to work:

Tell application "Finder" to set the sort direction of the modification date column to reversed
There is a bug in 10.7 and 10.8 where changing the sort direction doesn't always work unless you change the sort column first (see this question).

tell application "Finder" to tell list view options of window 1
    set sort column to name column
    set sort column to modification date column
    set sort direction of column modification date column to reversed
end tell
