Plugin Prioritization

Hi.

We have a custom plugin that delays the content (set it to scheduled state when author clicks on publish).

However we would need to set the priority of this plugin so it would start as the first one (now there’s the problem with Jetpack Social and other plugins, that consider the posts to be published immediately – so the post is shared, but it leads to 404 cause it’s not actually shared yet).

So the question is – how can we force this plugin to be executed before all the other plugins?

Thanks!
