Tile OS X Terminal window to Finder with AppleScript

I updated my AppleScript that will tile the terminal window nicely below the frontmost finder window.

For some reason setting the Terminal window bounds is very buggy. I resorted to using the deprecated methods {position and size} and have to loop it three times to ensure that it positions correctly.

I tied this to command-; in my app launcher, QuickSilver

tell application "Finder"
 --make new Finder window
 activate
 if not (exists window index 1) then
  make new Finder window
 end if
 set {x1, y1, x2, y2} to bounds of window index 1
end tell

tell application "Terminal"
 activate
 
 if (count of windows) is 0 then
  tell application "Terminal" to activate
  tell application "System Events" to tell process "Terminal" to keystroke "t" using command down
 end if
 
 -- For some reason it can take up to 3 times for Terminal to be properly adjusted
 set L to {1, 2, 3}
 repeat with xxx in L
  set {xx1, yy1, xx2, yy2} to bounds of window index 1
  set position of window index 1 to {x1, y1 + {yy2 - yy1}}
  set size of window index 1 to {x2 - x1, y2 - y1}
 end repeat
 
end tell
