Is priority gauranteed to make two DMA transfers initiated by the same trigger arrive at a static destination address in order?

I need to process samples from two different ADCs by transferring their samples to the FMAC via DMA. This is done by writing repeat values to FMAC->WDATA. Both ADCs have the same trigger and I want to insure one ADC's value arrives before the other. I know I can adjust the priority, but they are both using channels on DMA1 and they trigger at the exact same time, so I’m still suspicious there might be more to it. Is priority enough?
