You mis-copied the syntax: it's "dscl localhost -read ...". The output to groups or id should be equivalent, but this is checking resolution against the group vs. against the user. Off the top of my head, I couldn't tell you which way sudo does the resolution, but it's usually a good sanity check to resolve both ways in case something's flakey with the name service data.

Could you also provide the output for the grep against /etc/sudoers to show which lines for the wheel group have been uncommented and their order of appearance?
