Your problem is not here in TPL file. It is on PHP associated module file. You should look for module displaying products in home page (like blockbestsellers or blocknewproducts) and look for main PHP module file. Inside you should find the MySQL request. For example from blocknewproducts:
protected function getNewProducts()
{
if (!Configuration::get('NEW_PRODUCTS_NBR'))
return;
$newProducts = false;
if (Configuration::get('PS_NB_DAYS_NEW_PRODUCT'))
$newProducts = Product::getNewProducts((int) $this->context->language->id, 0, (int)Configuration::get('NEW_PRODUCTS_NBR'));
if (!$newProducts && Configuration::get('PS_BLOCK_NEWPRODUCTS_DISPLAY'))
return;
return $newProducts;
}
You should change this $newProducts = Product::getNewProducts((int) $this->context->language->id, 0, (int)Configuration::get('NEW_PRODUCTS_NBR')); for your own MySQL sentence keeping original behavior but avoiding random.
Good luck
