Not so long ago I wrote a script for prepending disc numbers before song numbers according to folder hierarchies. You can find the original script here:
The original script was designed specifically for working with FLAC files. I recognize that not everyone has my passion for sound quality or my devotion to this particular open-source format. As such I have updated that script so that it will accept a user-supplied file extension. This means that the version of the script you find below may be used for any number of file types (one at a time).
Same as previously, the script assumes that your discs are separated into folders called 01, 02, and so forth. So you will want to name your sub-folders accordingly (it will ignore folders with names such as Disc 1 or Physical Graffiti 1 or anything really that isn’t a two digit number).
Once you have renamed your disc folders accordingly, this script will begin at a folder you select and parse into that folder, seeking out all folders named with two digit numbers, and renaming all the files contained therein if they have the file extension you supplied.
Also, I like my file names to run album number dot track number (01.01 – Track Name.flac). You could adjust the script if you prefer a different naming convention.
(Use the pointy brackets button to copy and paste.)

I hope this serves you well. Feel free to send me questions in the comments.
