After some digging, I found it in a hidden preferences file called .GlobalPreferences.plist in my user's Library/Preferences folder. I found the same file in the top-level /Library/Preferences folder, and then added the com.apple.mouse.tapBehavior setting as a class of Number with a value of 1 and saved the file.
Now my login screen works the way I expect it to, and as an added benefit, new user accounts now default to having tap-to-click enabled.
[robg adds: The easiest way to add this key to the global file is to have Apple's Xcode Developer Tools installed. Then in Terminal, you can cd /Library/Preferences and then type open .GlobalPreferences.plist, and the Property List Editor will open.]
