Avodah Zarah 7: Was the Mishnah Written Out of Order?

Organizing the halakhah from the mishnah, in accord with its various opinions. Including the principle of a single unattributed view that follows a machloket (dispute) - when is that view followed and when discarded? How significant is the order? And how close in terms of proximity do these statements need to be? Perhaps there's no "sequence" to the Mishnah... at least not from tractate to tractate... [Who's Who: Nachum the Mede]. Plus, dill and tithing.
