Random products on pagination

[sallen_acs]

Hi,

Im trying to show the products on the categories pagination with a random order.

 

I found this interesting post:

But it has a module override as me.

It has a lot of queries and i dont find the place to change the "order by rand()"

The module its on the actionProductListOverride, and its blocklayered.php

I dont look so safe to attache a file, so i paste a git link if someone can help me to find where i can change to show my products with random order.
