I'm trying to write a code to import a selected band (1 Km Monthly NDVI,
for example) from a number of files, then subset through EVF, then save
it in a selected file format but I'm having problems on the import part.
I thought ENVI_SELECT can handle opening only a single band through pos
but I'm probably doing it wrong. Also, when I open a single file from
the MOD13A3 files and look at the available bands list I see it as three
"separate" file trees (one separate tree for the reflectances, EVI, and
NDVI).

Try The MODIS Conversion Toolkit plugin for ENVI from
https://github.com/dawhite/MCTK
Reads many types of MODIS data, both interactively and programmatically,
allow selection of bands, re-projection etc
