I don't know what speed differences there might be, but another option is
something like this..

function ipfunc pIp
   set the itemdel to "."
   set the numberformat to "###" -- force length of each chunk to 3

-- append the numbers together sans "." with padded 0's using numberformat
   repeat for each item tItem in pIp
         put tItem +0 after tIp -- do the add to force the numberformat to
work
   end repeat
   return tIp
end ipfunc

And then use it like so..
sort lines of myIpList ascending numeric by ipfunc(each)
