Is the "id" attribute a class property? It is usual that it is not. If it is not, then it will not be usable in this manner.

Keeping in mind the fact that the pk of the table should be something invisible outside the table, so that nothing outside the table can impose a meaning on it and thereby want to change it, why would you want to sort by the pk?

You should probably sort by something that means something. The pk should not mean anything. On the other hand, if you make the "id" attribute into a class property, the EOF gods will probably not smite you with righteous lightning and thunder. It just makes for a less clean schema design.
