Ok. I've posted a message and several comments about this problem and I've got some more information. I understand that Sublime uses TextMate syntax highlighting. I was told that since JSP syntax highlighting doesn't seem to work properly in Sublime, it is the fault of the TextMate bundle.
I just installed TextMate on an old Mac I have here in the office and VOILA--JSP syntax highlighting works perfectly. So I guess this is really a bug report. Either the developers are not including the latest Java/JSP bundle from TextMate (doubtful--I'm sure it is several years old) or there is a bug in the way Sublime reads these syntax definition files (this is my guess).
Basically, anything between the <? ?> tags is not being highlighted. I've tried to show this in this screen cap. It shows Sublime and my current text editor (TextPad):

If it isn't reading this syntax definition properly, it makes me wonder if there are others that aren't being read properly.
To the developers: thanks for a really cool editor. Keep up the great work. I hope to use it soon, but I do lots of JSP development.
