Apologies. But I'm not assuming here, I have experience with helping this person in a previous forum post where I helped him over IRC.

The script I'm referring to is this:
Click to reveal..
What he's using is a variant of this, I don't have access to his specific script, but it's highly based off of this.
Code:
alias -l addPoints {
if ($1 !isnum) { echo 2 -st $1 is not a number. It needs to be a number. | halt }
var %topic $+($chan,.,$nick)
var %points $calc($readini(Points.ini,%topic,Points) + $1)
writeini -n Points.ini %topic Points %points
return %points
}

alias -l lookUpPoints {
var %topic $+($chan,.,$nick)
var %points $readini(Points.ini,%topic,Points)
return %points
}
alias doaddpoints {
if ($3 !isnum) { echo 2 -st $3 is not a number. It needs to be a number. | halt }
var %topic $+($1,.,$2)
var %points $calc($readini(Points.ini,%topic,Points) + $3)
writeini -n Points.ini %topic Points %points
echo -a Added points for %topic
}

alias dorempoints {
var %topic $+($1,.,$2)
remini -n Points.ini %topic Points
echo -a Removed points for %topic
}

on *:text:!points:#:{
if ((%floodpoints) || ($($+(%,floodpoints.,$nick),2))) { return }
set -u10 %floodpoints On
set -u30 %floodpoints. $+ $nick On
msg # $nick has $readini(Points.ini,$+(#,.,$nick),Points) total DePoints.
}

on $*:text:/!points (add|remove)/Si:#:{
if ($nick isop #) {
if ($0 < 3) { msg # Insufficient parameters: Use !points <add|remove> <user> [number] | return }
writeini -n Points.ini $+(#,.,$3) Points $calc($readini(Points.ini,$+(#,.,$3),Points) $iif($2 == add,+,-) $iif($4 isnum,$4,1))
{ msg $chan $3 now has $readini(Points.ini,$+(#,.,$3),Points) total points. }
}
else { msg $chan This command is only available to moderators. }
}
on !*:join:#:{
$+(.timerpoints.,#,.,$nick) 0 300 add.pts $+(#,.,$nick)
add.pts $+(#,.,$nick)
}
on !*:part:#:$+(.timerpoints.,#,.,$nick) off
alias -l add.pts {
writeini -n Points.ini $1 Points $calc($readini(Points.ini,$1,Points) + 5)
}
Taken directly off of another forum post.
What it does is increase a value in an ini file with a timer. The output looks like this:
$mircdir\Points.ini
[#channel.$nick]
Points=1

[#channel.$nick]
Points=123

etc.
It automatically starts a timer for every user on the join event and will also write to the file on join, which means that every user that hops into his channel will be logged in that file, making it extremely slow after a high number of data has been logged.
