sparse TODO tree and priorities - with a custom face

[Ram Bhamidipaty]

I understand that org-priority-faces is only used for agenda views. 
However when viewing TODO items I find that the lack of additional 
context in the agenda view makes thinking about the TODO items more 
difficult.

Whereas with a sparse tree the TODO items are presenting with the 
associated positions in the hierarchy, which is very useful for me.

What I want is a way to visually see the high, medium and low priority 
items. For example "A", "B" and "C" items could be shown in a different 
color.

How can I do that?

Thanks for any info.
