I was checking the rank of my guild realtive to the others in the list and discovered that they change position depending on which guild is in focus.

What I did is this:
Select EU-Ravenholdt and Horde
If I click on Crimson Tide it figures as number 12 in the list
If I click on Dark Omen (or one fo several other guilds), Crimson Tide then jumps up 2 places to number 10

This makes the listing pretty useless for real comparison of guild sizes. I have reproduced the bug with 2 machines over the last 2 days with both Firefox and IE 7

The reason this happens is due to the way the pages are generated and cached. For example, when you pull up Crimson Tide, you are likely looking at a cached version of the page. You then clicked on Dark Omen, and perhaps it has to generate that page fresh, which also hits fresh data, hence reordering the guilds a little.

Basically what you saw was an older cached version of a page versus a newer version of the page which is utilizing fresher data.

This should be a fairly limited problem as the cached versions are supposed to be wiped at least every 24 hours.

And since I just flushed the cache, you'll notice that Crimson Tide is always in place 10 for the Horde side. This will remain true until some data is processed that would change the ordering.
