I have the same need.
In the order confirmation page I have the main tag for analytics, and others for marketing campaigns. I need to run the former before everything else starts, in order to avoid any loss of data. The tag order that we use in Tealium affects the order utag loads each tag, but does not manage what they do. I mean, usually the analytics tag takes a long time to run more than any other tag, so it will fire the pixel at the last moment. Even if I use the WAIT FLAG=OFF for the analytics tag, I noticed that the other tags, if cached, could run before anyway.
So, do you suggest not to load other tags in the order confirmation page, and load them after a delay using something like the setTimeout() function?
Thanks,
