Regions in nodes

Hi I have implemented regions in nodes (D6.17), all works fine but the order of the blocks displayed in one region is inverse to what they are in the build/block/list page. Does anyone konw how to fix this ?

I use this to enable the regions in my template.php

// enable regions in node.tpl.php

function netmx_preprocess_node(&$variables, $hook) {
$variables['teaser'] = theme('blocks', 'teaser');
}

Thanx
