$ scala

-bash: /usr/bin/scala: Permission denied

The file in /usr/bin isn't the binary itself, but a symbolic link (symlink) to the "real" binary at /opt/scala/scala-2.10.1/bin/scala. In order to execute your command you need to have sufficient permissions on that file, not (only) on the symlink. Otherwise, permissions could be circumvented very easily, just by creating a symlink with less restrictive permissions.
