Honestly, I never did that, seems like a waste of an early Tradition policy and since the patch sent Legalism down a notch, it's absolutely crazy not to go down Tradition before taking anything else.
I did however go Liberty and then opened Tradition for HG, that kind of makes more sense because you get +3 culture per turn which in the early game kind of makes up for a detour policy
Liberty (Just until Free Settler)
Tradition
Rationalism
Order (Or Autocracy)
...
Win
On what difficulty level?
I only choose Liberty when I have a jungle start. That is the only time that liberty is better than tradition that I have found.
^^eh, regular pillage-heal-repair works well enough that this is not enough reason on its own to pick Liberty...
