This is _very_ annoying.

Because you can (actually, you do) define whatever order you want in
the ENUM declaration (even alphanum order).
 
The way it works now, I have to know in which position the label
'good' is to construct the select. I think this leads to unnecessary
duplication (is there a function that returns the position of a label?
I couldn't find it in the manual).

IMHO, if it were abstracted away by the server we would have better
functionality.
