change parent child task relationship with AppleScript
 

Hello,

I am trying to change the parent-child relationship between two existing tasks. I have seen an example for adding a new child as:

[CODE]set parentTask to make task with properties {name:"draw floor plans"}
tell parentTask
make task with properties {name:"draw first floor"}
make task with properties {name:"draw second floor"}
end tell
[/CODE]

but I can't figure out how to do that with an existing task (assume parentTask and childTask are already set)

[CODE]tell parentTask
add childTask to child tasks ???
end tell[/CODE]

[CODE]
move childTask to end of child tasks of parentTask
[/CODE]

Also:
[CODE]
move childTask to after item 3 of child tasks of parentTask
[/CODE]
(before and beginning can be used in place of after and end, respectively)
