If the code above were compiled into a tail call, the foo:return probe would fire before the bar:entry probe. The value of arg1 or args[1] will not contain the value returned to the caller of foo().
Many thanks for the clarification. May I suggest that the fbt chapter in the DTrace wiki be updated to reflect this? The section on Tail-call Optimization discusses the difference in ordering, but I don't think that the effect on args[1] follows.
