sort doesn't work in binary mode properly.
Just figure out, how many people uses sort in their scripts. In example,
vim+ctags doesn't work, cuz ctags uses sort as external sort program, and
vim by default doesn't understand unsorted tags files.
sort is paying attention to locales now. What's your locale setting?
It's not a bug, it's a feature - the new sort is POSIX compliant, therefore
some flags have changed. (See info sort)

While this isn't a bug in sort, isn't it a problem with the RH6.1 distribution that the default installation doesn't set the LC_ALL variable to work with sort 2.0? Considering how many people depend on the sort command, it shouldn't take additional tinkering to install RH and have a usable sort.
