New description:
Or did someone already implement them?
Here's my code. Its weakest point is probably the input; instead of an
actual pair of a poset and a map from its elements to {1,2,3,...}, it
takes a pair of a poset and a linear order on it represented as a tuple of
its elements. (See docstring for details. By the way, I'm hoping the LaTeX
does work... no idea how to check that.)

Comment (by chapoton):
the review patch introduces a typo "parition", that needs to be corrected
