Sort produces different results when sorting strings with non-alphanumeric
characters, depending on the operating system:

RHEL 5.2, R 2.10.0
-------------
> v <- c("1","<0",">3","2")
> Sys.setlocale("LC_COLLATE","en_US.UTF-8")
[1] "en_US.UTF-8"
> sort(v)
[1] "<0" "1"  "2"  ">3"

Max OS 10.5.8, R 2.10.1
-------------------
> v <- c("1","<0",">3","2")
> Sys.setlocale("LC_COLLATE","en_US.UTF-8")
[1] "en_US.UTF-8"
> sort(v)
[1] "<0" ">3" "1"  "2"
