Quoting resolv.conf(5):
       nameserver
              Internet address (in dot notation) of a name server
              that the resolver should query.  Up to MAXNS  (cur­
              rently  3) name servers may be listed, one per key­
              word.  If there are multiple servers, the  resolver
              library  queries  them  in the order listed.  If no
              nameserver entries are present, the default  is  to
              use  the  name  server  on the local machine.  (The
              algorithm used is to try a name server, and if  the
              query  times  out,  try the next, until out of name
              servers, then repeat trying all  the  name  servers
              until a maximum number of retries are made).

What you're suggesting doesn't help--the system will always just use the
first three nameservers. You'll never know because they'll work
perfectly well, but there are the issues of wasted bandwith and
potentially longer response times.
