well, I'm really not sure how to answer your question since disc 3 only has 16 tracks... lol check your track numbers and get back to me.
If you mean track 17 on Disc 2 and Track 16 on Disc 3, the difference is this:

In the original 70mm cut of the film, the ending sequence was different in two ways: There were less effects shots but there was more dialog. Because of this, Williams wrote what you heard on Disc 3 which has an extended section near the end before the final grand statement of Han and Leia's theme and then into the end credits.

The only released version before the SE's was what you hear on track 17 on Disc 2. This is a re-score for the shortened, but yet lengthened sequence seen today.

There were effects shots added to the beginning of the sequence, but some of the dialog was cut and so Williams re-scored the scene with this take which doesn't have that section near the end before the final Han and Leia theme statement.

In the film, tracked music was brought in for when the Lando is prepping the falcon to leave for Tatooine. Then we hear whats a mix of the two versions.

The end credits however has two versions which are really the same but simply edited differently.

The one on Disc 2 is NOT the film version but is the easier to listen to of the two and has less jarring edits.

The one on Disc 3 IS heard in the film. Notice the strings disappear on the first note of the Imperial March segment in that one, but in the Disc 2 version, they play. That plus about 3-4 other edits differentiate the two versions. They're just different edits. Both have been released.
