Well, of course -- in the extreme case, you can associate a number
with every single index term and have complete control over sorting.
But even if don't go to the extremes, I think these tweaks are OK
occasionally, but if you start using them systematically in a large
document, after a while these will become confusing.  Especially if
such index terms are generated automatically, like in Adam's case.
