Well, lets create a Boolean Attribute: Ladders. In your character, create rule: when actor collides or overlaps with Ladders, Change Attribute Ladders to true.
Then, in another rule, say: When Attribute: Ladders is False, And add all your character's normal motion. Otherwise, When Attribute: Ladders is True, then add the going up and down rules.

This should work, I actually haven't tried it.
