How do I scroll to the top of a window using applescript?

Script:

tell application "System Events"
   tell application "Safari" to activate
   delay 0.5
   key code 119
end tell

Simply run this script with NSAppleScript:

NSAppleScript *scrollDownSafari = [[NSAppleScript alloc] initWithSource:@"tell application \"System Events\"\ntell application \"Safari\" to activate\ndelay 0.5\nkey code 119\nend tell"];
[scrollDownSafari executeAndReturnError:nil];

EDIT

Better readable code:

NSString *script =
@"tell application \"System Events\"\n"
 "tell application \"Safari\" to activate\n"
 "delay 0.5\n"
 "key code 119\n"
 "end tell";

NSAppleScript *scrollDownSafari = [[NSAppleScript alloc] initWithSource:script];
[scrollDownSafari executeAndReturnError:nil];
