: Two solutions, one with 102 characters and the other with 89. (Can it be

:     ($u,$l,$f)=split(/[|\n]/),push@a,$l?$f?"$l, $f":$l:$f||$u
:     while<>;$,=$\=$/;print sort{lc$a cmp lc$b}@a

84 characters:

    print sort{lc$a cmp lc$b}
    map{/(.*)\|(.*)\|(.*)/;($2?join', ',$2,$3||():$3||$1).$/}<>
