Move keyboard focus from the sidebar to a playlist in iTunes

tell application "System Events" to tell process "iTunes"
	--tell outline 1 of scroll area 2 of window "iTunes"
	--set statictexts to value of static text of rows
	--repeat with i from 1 to number of statictexts
	--if ((item i of statictexts) as text) starts with "untitled playlist" then
	--set value of attribute "AXSelected" of row i to true
	--end if
	--end repeat
	--end tell
	select row 1 of outline 1 of scroll area 3 of window "iTunes"
end tell

The select command does highlight the row on gray, but the keyboard focus stays on the source list.
