Trying To Imitate AVERAGEIF() With An OR() Test.

I've got a spreadsheet I use to track quality scores, it will appear like such, and with 2003 I don't have AVERAGEIF()

name | team | score
joe f | billing | 3
may r | billing | 3
roy m | status | 1
kay t | first call | 1
etc...

I already used an array function to find the average of each team (even with empty scores) by using:

=AVERAGE(IF(DeptRange=$B$7,C$20:C$200)) [Ctrl-Shift-Enter]

EDIT: Incidentally, I changed AVERAGE() to COUNT(), and it kicked back 9 values instead of 3 (I have one value entered for each team atm). B7 is the name of the department I'm finding the average for. I've got 3 departments in one location, and 6 in another location. I'm trying to add OR() to give me our regional quality averages, and it's not working. I used:

=AVERAGE(IF(OR(DeptRange=$B$7,DeptRange=$B$9,DeptRange=$B11),C$20:C$200)) [Ctrl-Shift-Enter]
