There is an interview with Rupert Neve in which he states that the order of tracks in a DAW alter the sound of the mix. It's nonsense, of course.

Not at all! When you have 125 tracks, it's a hassle to scroll all the way down to the bottom ones, so people forget they exist . Alone and forgotten, like castaways on a desert island, they remain at the level at which they were recorded in perpetuity.

I tend to change orders throughout a mix. The main exception is the drums. If I have a kit I keep all the drums on the same colored tracks and in one place usually into a drum buss. 
 
The reason I move tracks is because I can see the wave forms compared better. If It seems something isn't lining up, I might drag the tracks in question close to one another and spread out the wave forms to get a better idea on the alignment. It's easy in Sonar, just grab the track and drag it.

I can dig that. FOH at church can get out if hand.

I see the logic, but when I want to compare waveforms I just select the 2 (or more) tracks I'm interested in and hit ctrl + shift + h to hide every other track and maximise the remaining ones in one go.

I gotcha, I used to be a professional photographer also, so I get the PS reference. Track order doesn't matter sonically, but it does in work flow. If you have a consistent layout, you will be able to work faster. As with many things I guess we all work a little differently. There aren't absolute rights and wrongs. Flexibility is what makes these modern DAWS great.

Funny topic ,, but it made me realize I put my tracks  somewhat the way I've always set up a FOH mixer. 
Vocals in first channels left to right across the stage, then the instruments  and then drums on the far right in what ever channels where left over. So my Sonar track view has the Vocals at the top and drums at the bottom with everything else between. If I open the console view it look the way I like.  I think it does sound better this way!! 

Top to Bottom, my projects always run Drums > Bass > Electric Guitars > Acoustic Guitars > Keyboards > Vocals > Special Fx, all in separate folders.
 
Within each folder, the tracks are always set out so the the top track is the instrument that "speaks" first, apart from drums which are Kick > Snare > Hat > Toms > Cymbals > Percussion.

Whatever works. It is good to share tips though.

It's interesting to see how many different ways of doing things there are. I was hesitant to ask this question, but I'm glad I did now.

I guess I always put vocals on top (left side of mixer equals top in DAW, then guitars, on down.
