I"m sure it's a matter of editting the source code and changing the html, but still, it would be a headache if you just had to have a particular host at the top, etc. I'm sure you can see how that would be impossible to manage as you add more and more host checks.
Luca's suggestion is the only EASILY managable way to do it.
If you don't want to change your host names, then you could easily add 0001 and 0002, etc to the from of the name of your hosts that need to be at the top. Now that isn't gonna take much time, and can be managed. So don't waste your time with changing the source code.
