On the Collect side it wouldn't be a problem. Even if delivery reports end up being reported it won't matter what order those come back in.
It will be up to the receiving end to handle order for data presentation and further analysis. Any service natively capable of receiving multi-part SMS (e.g. Android/iOS default messaging apps, Twilio and most other SMS gateway services) do this implicitly.
Those building custom receiving solutions may need to read the user data header and recreate the order. If they use an API like Twilio's this will be done seamlessly.
