You might want to use "wb_command -cifti-parcellate" to do this for you, it has some extra options to do things like weighted means according to vertex area.
Manually matching things up in matlab from loaded cifti files may be difficult, as some .dlabel.nii files don't exclude the medial wall, and may not include the subcortical voxels that the .dtseries.nii files do. You can use -cifti-separate on cifti files to make simpler single-hemisphere full-surface gifti files, and a nifti volume file for the subcortical stuff (though doing this on the timeseries will result in a fairly large volume file when loaded in memory).
