Strangly behaving Commandblock behaviour in term of trigger timing

In more early and stable builds i was used to put my Commandblocks into a specified order in which they get updated (the Commandblocks at th x-Axis got updated first, after this the ones at the next next z-Axis would update and after this the ones at the next y-Axis would update).
However, there is no such order in the current snapshot. The update timing of the Commandblocks isnt completly random, sometimes strange enouth to call it random though. Will there be an update to this so the Commandbloks will work as they are used to?
Sorry for my broken englich!
