Not sure if I understand your question - encryption in dmcrypt works on sector level, sectors are encrypted independetly, so order cannot influence result of encryption of individual sectors. Or if the question is about order of submitted requests: If you need to ensure order of processing, you have to issue "flush" operation before submitting next data content. Filesystems typically must do this when handling journal or so. In general, requests order can be rearranged (anywhere in block layer, not only in dmcrypt). But this is correct behaviour.
