Short determines what happens after SoS

Recently I was again checking out the SoS cursor values: http://pastebin.com/aqixJkV4 And I wanted to mess with it some more. I wanted to know why it sometimes gave different cutscenes and warp locations. After a bit of digging, I found the short which decides what to do after you select your warp destination on the SoS menu.

When you use a glitched cursor value w/ SoS it will assign a value to this short and then based on what this value is, different things can happen to link. These are the results:

0    Softlock
1    Softlock
2    Softlock
3    Softlock
4    Gain control again (It's normally this value when you just have SoS menu up)
5-21 Softlock
22   Song of Time: Resets cycle & puts you in SCT, doesn't save.
23   Softlock
24   Speed up time CS
25   Slow down time CS
26   SoDT cutscene (Doesn't advance the day at all)
27   Softlock
28   Soar to Great Bay
29   Soar to Zora Cape
30   Soar to Snowhead
31   Soar to Mountain Village
32   Soar to Clock Town
33   Soar to Milk Road
34   Soar to Woodfall
35   Soar to Swamp
36   Soar to Ikana
37   Soar to Stone Tower
38   Soar to last entrance
39+  Softlock (I tested up to 200)

If somebody can find out what determines the value written into this short, we should be able to easily find all the cursor values which lead to the cool and unique results, like the soaring ones and the SoT one.
