I'm afraid we can't definitely say whether you would receive points or not as it will be dependant on how you describe your problems.
The requirement is that you can reliably, on the majority of days, stand and move (walk).
Reliably is explained in the PIP Claim guide.
So you need to explain how far you can walk reliably, and how your ability to walk reliably varies over a week or a month as applicable. If you can show that you cannot reliably walk more than 20m on the majority of days then you are assessing your self as scoring 12 points.
