I have just being looking at the PIP assessment wording for the mobility component and I am puzzled by the logic in the scoring. To me, A, below, means the person cannot undertake any journey at all. B means they can undertake familiar journies if they have support of some kind. So why does B score more points than A?
Crucially A is below threshold and B is above 
A. Cannot undertake any journey because it would cause overwhelming psychological distress to the claimant.
B. Cannot follow the route of a familiar journey without another person, an assistance dog or an orientation aid.
