I can perform the Projectile and Rolling Elbow, but not the tornado special.. (I know the command it's shoryuken motion..)
The Hiryu Shoten Ha is kinda sticky for me too...I meant to report that, but since you mentioned it first, I did a little investigation.
The CMD is missing the defaults section that defines how much time commands are allotted for input. Kinda looks like this (using one of my creations as an example...)

The Mouko Takabisha and HSH's commands are written without the 'time' parameter, and since the defaults section is missing, I'm thinking it affects how those two execute.
'Course, I'm no expert, but I guess it's a good start at guessing. I'll experiment a bit and get back to ya'll.
