Here's my attempt at a list of 'official' tier 4 modules, either released with the ampersand (official D&D content released by wotc), or without the ampersand but still by WotC's Adventurers League team (not necessarily the same 'officialdom' as content released with the ampersand). The list is a work in progress.
