Change the Stereo tracks in the new sequence to Mono tracks before you paste in.
Sounds like you're creating a nested sequence? You're dragging the sequence icon into the other sequence?
If you want the tracks separate, you're best to open the sequence, copy the contents, and then paste into the new sequence. That will give you all the tracks/individual clips.
Although your answer is correct, and may be the only correct answer, it's not very helpful.
I don't seem to be able to export a digital intermediate that has more than one audio track.
What I'm thinking of doing is soloing individual audio tracks and exporting audio-only files to accompany my video, then multiplex the audio in some other piece of software. I know Premiere's not meant to be an audio package, but surely there's a better method?...
That seems like a separate issue. What other piece of software will you be working on the audio in?
We export OMFs with multiple channels of audio for sound mixing all the time. You can also export AAFs. It depends on what the audio software can handle.
You can only export videos with 2 channels of audio, but that's not the best way to get sound into a dedicated audio app. I do wish you could export movie files with multiple audio channels though. I'm contractually obligated to deliver four channels of audio, which means I can't use Premiere as a finishing tool.
Well, my co-worker wants to do the audio. My only obligation is to somehow get the audio to her in an editable state. I think the obvious thing to do is to give her the video as a reference, and multiple .wav files, each of which represents some audio. We have numerous narrators each reading a line of a script. For example, I could put every odd numbered clip's audio on track 1 and every even numbered clip's audio on track 2. Then her job is to combine the two audio tracks in whatever way she chooses. If I put in cuts or dissolves then she loses part of the clip and it limits her options. Is there a better way?
Is there a better way?
Yes, absolutely; OMF or AAF export.
What software is she using to do the audio?
She hasn't decided what software to use. In fact, since she's a rock chick, she might even use real-time hardware.
a digital intermediate that has more than one audio track.
That feature only became available with CS6. But good luck finding out how. The new Help system is frustratingly impossible to work with.

OMF is the solution to what was not a very well phrased question by the O.P
