Subject Rewrite Based on Score

[Shane Webster]

Spamassassin Version 3.2.5

I am curious if it is possible to rewrite the subject based on the value
of the score. A example of this would be if a score of 4.0 was given the
subject would state [Potential Spam], but if it was 5.0-10.0 then it is
[SPAM] if it was greater then 10.0 it would be [SUPER SPAM]. I
understand this may seem odd but I am just trying to fill the request of
the client and what they want.

I would appreciate any incite, I am willing to do the scripting for this
if needed, but I would appreciate a point in the right direction
please. 

Thank you,
