You don't need parentheses in this particular construct anyway, so just take them out. Your syntax for comparing the output is not correct, though.

Anyway, this looks needlessly complicated. Perhaps simplifying the script would be a better way to spend your time.

Is /etc/defaultrouter a single line?

Code:
#!/bin/sh

read value </etc/defaultrouter

case $value in
  *[!.0-9]*) value=`awk -v v="$value" 'v { print $1 }' /etc/hosts` ;;
esac

awk -v v="$value" '$1 == v { print $2 }' LIST

defaultrouter

defaultrouter(4)						   File Formats 						  defaultrouter(4)

NAME

       defaultrouter - configuration file for default router(s)

SYNOPSIS

       /etc/defaultrouter

DESCRIPTION

       The /etc/defaultrouter file specifies a IPv4 host's default router(s).

       The format of the file is as follows:

       IP_address
       ...

       The  /etc/defaultrouter	file can contain the IP addresses or hostnames of one or more default routers, with each entry on its own line. If
       you use hostnames, each hostname must also be listed in the local /etc/hosts file, because no name services are running at  the	time  that
       defaultrouter is read.

       Lines beginning with the ``#'' character are treated as comments.

       The  default  routes  listed  in this file replace those added by the kernel during diskless booting. An empty /etc/defaultrouter file will
       cause the default route added by the kernel to be deleted.

       Use of a default route, whether received from a DHCP server or from /etc/defaultrouter, prevents a machine from acting as an  IPv4  router.
       You can use routeadm(1M) to override this behavior.

FILES

       /etc/defaultrouter	       Configuration file containing the hostnames or IP addresses of one or more default routers.

SEE ALSO

       in.rdisc(1M), in.routed(1M), routeadm(1M), hosts(4)
