See the manual ("man 5 dhcp-options").

                                                         Options which are not
     listed by name may be defined by the name option-nnn, where nnn is the
     decimal number of the option code. 

You can only specify options by number if the dhcp client doesn't know
the syntax/semantics for that particular option.
