You are correct about ECMP, I encountered this 12+ months ago and forgot that specific details. Mark said he put the whole AE bundle into per packet mode [on a short LAN hop], which can also cause reordering [not just the LSP] if used incorrectly.
Yes, I've specifically disabled control word. For us, disabling control word avoid LSP contents being sticky to a single LAG member. It worked for us, in that it solved a congestion issue carrying a high bandwidth LSP mixed with internet traffic on a two link bundle. We are 100% Trio forwarding shop and avoid L3 ECMP [LACP only, with links having essentially the same latency characteristics]. YMMV, as I've been strongly reminded.
