Perhaps what SoloCDM really wanted was to execute the command only if the
original command succeeded, in which case you'd want:
command1 && command2 && command3
assuming the shell is /bin/sh or /bin/bash.
In order to nice those processes, you'd have to tell the shell you meant
all of them:
nice /bin/sh -c "command1 && command2 && command3"
or make it a shell script (which is essentially what the above does).
