If i remember correctly... you also said you had 14 words to choose from (as opposed to just the normal 12)...
Given that you're unsure of the actual words used in your seed menmonic and their order, is it also possible that you had a seed mnemonic where a word was used twice? I've seen seed mnemonics like this before... in fact, I helped a guy recover his seed mnemonic where he only had 23 words out of 24... turns out he failed to notice a duplicate word when he was writing them down!
What process were you using to store/record your mnemonic that resulted in confusion of words and order?
One other thing to consider... the possibility that you used a passphrase? I know that Mycelium doesn't allow for passphrase functionality as standard... but I believe it is possible to "restore" an HD account using a passphrase with Mycelium

There was no duplicate words, no. I took the 12 words I was most sure about using, and added two which I was 50/50 if I had used. I have now run through 95% of the possible seeds with no success.
I took the seed, mixed the index of them with a 12 digit number I hold close to my heart, and then wrote a small text about it. In that way it could be hidden in plain sight.
Problem is I now, one year later, realize that it was pretty easy to just make up a story and accidentally throw in a couple of words that happened to be on the bip39 wordlist....
Passphrase was something that struck my mind. However I am sure I didn't do any complicated or different steps in the app other than create backup and write down the words, I see that possibility as none.
