Looks like you'll have to specifically set that variable to zero to avoid the no such variable error.

when CLIENT_ACCEPTED {
  set issue_redirect 0
  log local0. "client address: [IP::client_addr]"
  if { [IP::addr [IP::client_addr] equals 156.74.138.63] } {
    log local0. "matched address 156.74.138.63"
    pool GWWEB-HTTP
  } elseif { [IP::addr [IP::client_addr] equals 156.74.12.223] } {
    log local0. "matched address 156.74.12.223"
    pool GWWEB-HTTP
  } elseif { [IP::addr [IP::client_addr] equals 156.74.12.222] } {
    log local0. "matched address 156.74.12.222"
    pool GWWEB-HTTP
  } elseif {not[IP::addr [IP::client_addr] equals 156.74.16.0/24] } {
    log local0. "matched subnet 156.74.16.0/24"
    set issue_redirect 1
  } else { 
    log local0. "didn't match any addresses"
    pool GWWEB-HTTP
  }
}
when HTTP_REQUEST {
  log local0. "issue_redirect: $issue_redirect"
  if { $issue_redirect == 1 } {
    log local0. "issuing redirect..."
    HTTP::redirect "http://inweb.ci.seattle.wa.us/ccss/noaccess.asp"
  }
}

Give that a whirl...
