Nice effort, Linuxuser, with the socket. One helpful advice for you is to use the /sockmark command instead of setting a bunch of global variables:

on *:text:$($iif(!stats * iswm $1,$1)):#:{
  if !%f { set -z %f 5
    sockopen mstats www.relentless.ws 80
    sockmark mstats $+(/mstats.php?n=,$2,-,msg #,-,$2,-,/All|Act|Ra|Fo|St|per|Unt|Cov/)
  }
}
on *:SOCKOPEN:mstats:{
  tokenize 45 $sock(mstats).mark
  sockwrite -nt $sockname GET $1 HTTP/1.1                                  
  sockwrite -nt $sockname Host: $+($sock(mstats).addr,$str($crlf,2))
  sockwrite -nt $sockname Connection: close
}
on *:SOCKREAD:mstats:{
  tokenize 45 $sock(mstats).mark
  var %mstats | sockread %mstats
  if ($regex(%mstats,$4)) {
    $2 12 %mstats
  }
}

it does look a lot cleaner, doesn't it? No timer is necessary...
Although the script gets a bit bigger, it's better this way.
