actually, even that doesn't sort it in some cases.

i've recently corrected a similar bug report for footmisc by switching
to doing that calculation using the etex primitives if available.
(i.e., i've corrected for users of a modern distribution.  however,
the only way to make it totally robust is to go for arbitrary-length
calculations: someone _else_ is welcome to write efficient macros for
that, but i'm not going to dig into packages like fp ... numerical
analysis was my poorest subject in my final exam in 1968 ;-)
