You could try using the new MODIS Conversion Toolkit plugin for ENVI:
http://www.ittvis.com/codebank/search.asp?FID=485
It can handle MOD07 data, along with every other know MODIS product
(143 at last count). There is a GUI version and a fully-accessible
API. I tried to make the programmatic interface as easy to use as
possible. If you do try it out, and run into any issues, please let
me know. I'm always looking for ways to improve it.

I think that the most important part of your program probably isn't
the part where you select which band to display. What does the code
look like that you used to create the original JPG file?

I'm moderately familiar with the use of the envi GUI, but have no
experience with it's programming interface. However, reviewing the
Envi Help, I couldn't find anything obviously wrong with the code
above.
