Setting the default todo priority ?

[David Masterson]

I see that Org treats TODOs without a priority cookie as having a
priority that is midway between highest and lowest.

Use case: I may have a task type that fully expresses what it's priority
is.  Example would be SOMEDAY which is going to have the lowest
priority.  Adding a cookie to all SOMEDAY tasks seems superfluous.

Is there a way of changing the default priority?
