Unsure about random delay, but it's quite possible to give it a certain delay using macros to heal, kinda like this:
LowLife%:=99
Self.Health%<!LowLife%!
Hotkey.Use(ID)
Using automatic macro in whatever ms you want (you may want a higher value than 1000 ms so it doesn't look like bot heal). As the auto macros are always running, the healing tempo will already be kinda random, so I guess it solves your problem.
