It's a so-called build number. For an application this is usually increased every time the developer compiles, and packages the app. For an OS, which is composed of multiple apps and other things, it's probably each run of an automated process.
Build number or coded best before date? . Build number seems a logical explanation, so I would think that any beta version would have a lower build number than the actual final release version.

As we have known for a long time - rim never serves it before its time and then adds six months just for grins.
If you ever do any programming you'll know that developers do extensive testing of every feature, they are almost instinctively hitting the compile button (like how you instinctively hit the save button on a word document). Every time that is done in most compiling software it increases the build number by 1. so it was build 7971 times (7971 being the final). I assume that their software will go as many digits as it needs, so it could say 2.0.0.10234 if it needs to.
Edit: I should note that this would probably be the combined total of all the developers, not one guy.
