I would call it drums.

It's a song of suspense? Is there any more specific name?
At this time (screenplay), Lisa is packing to leave your home.
P.S. I'm writing a movie.
It's not a song. I guess we have Apple and iTunes, etc. to thank for this loss of distinction, which must bug many musicians. It certainly annoys me (as you can probably tell), especially when I hear well known symphonies and concerti and people ask "Oh, I love that song. What is it?"
A song has someone singing in it. (And don't mention Mendelssohn's 'Song Without Words". That's an exception that proves the rule.)
If you're writing a movie, only some of the music and sound effects will be songs.
If you're writing a screen play, you will annoy the director and producer to no end by telling them what music you want playing. That's what their job is.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
It is a musical piece, not a song. I would call it dramatic drumbeat.
You are making a movie, not writing a movie. You wrote an original screenplay.
If the piece was longer and more elaborate, it might be called a theme song.
This is very similar to your piece -- especially the beginning and the end.
This video has been deleted by YouTube. It was the Terminator 2 opening theme song.
