I suspect that ac3 in avi simple is rather uncommon nowadays and that is why Premiere is lacking there.
I don't use Premiere so no need to send the samples, but you can check if there's a difference in Premiere depending on whether ffmpeg or mp4box was used for the mp4 muxing.
I'll probably look into mencoder some more and see whether I can find a workaround or it's issues, if not I'll simply remove it for muxing if multiple streams are used inside the .avi container. 'Config > Containers > Avi: Always use ffmpeg for muxing' will probably get removed if I don't find a workaround.
