nice is a csh builtin which uses a different (historic) format

(cartman)38# nice -n -20 /bin/ls
nice: Badly formed number.
(cartman)39# which nice
nice: shell built-in command.
(cartman)40# whereis nice
nice: /usr/bin/nice /usr/share/man/man1/nice.1.gz /usr/src/usr.bin/nice
(cartman)41# /usr/bin/nice -n -20 /bin/ls
list of files
{cartman}42# nice -20 /bin/ls
list of files

Did you change shells between releases?  Maybe bash uses the new format.
