That should have been the opposite:

But I finally found a workaround using the synaptics driver.

I don't have an xorg.conf file so I tried adding Michael's suggested 
settings in /etc/X11/xorg.conf.d/50-synaptics.conf but that had no 
effect. Maybe the identifier string was wrong or more likely the 
configuration section just cannot stand on its own.

So then I copied /usr/share/X11/xorg.conf.d/70-synaptics.conf to 
/etc/X11/xorg.conf.d and added the TapButton lines to the section titled 
"Default clickpad buttons". So for me that section now reads:

# This option enables the bottom right corner to be a right button on clickpads
# and the right and middle top areas to be right / middle buttons on clickpads
# with a top button area.
# This option is only interpreted by clickpads.
Section "InputClass"
        Identifier "Default clickpad buttons"
        MatchDriver "synaptics"
        Option "SoftButtonAreas" "50% 0 82% 0 0 0 0 0"
        Option "SecondarySoftButtonAreas" "58% 0 0 15% 42% 58% 0 15%"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
EndSection

And that finally got me tap-to-click with the synaptics driver, without 
breaking right-clicks. It's sad that getting such basic functionality 
working feels like a breakthrough :-(
