I would opt for time based animations i.e. not dependent on previous 
pictures/frames. Imagine a huge - one cut! - space fighting scene with 
lots of ships, missiles, laserbeams and debris ending in a giant  
explosion of a space station which has impact to many surrounding 
ships. And now you are finetuning the end part and jump around a 
certain frame. Everey time you move some milliseconds back the *whole* 
fight with thousands of moving objects have to be recalculated! That's 
a pain!

And it's possible to make "strange" and physically unrealistic moves 
with the time based model too.

Another point is changing speed and/or fps. If you have a clock based 
model it's quite easy to double the frame rate, whereas a dumb script 
which relies on the previous frame to move an object might move it much 
too far.

And finally the underlying renderer supports the time based model 
natively with the 'clock'. I think many movements/effects can be 
implemented as POV-Ray functions. IMHO POV-Ray itself should be 
supported as scripting language too.
