I usually use a #switch statement to make the different "stages" of the
animation - something like this (and I usually let each clock unit be
equivalent to one second):

#switch (clock)
  #range (0, 1)
  /* First part */
    #declare Clock = clock; 
    /* Everything in the scene uses Clock in stead of clock,
     * so that I can play around with the clock value. */
    #declare BallRot = <Clock*200, 0, 0>
    /* Rotate the ball 200 degrees during the first second */
  #break
  #range(1, 2)
    #declare Clock = clock - 1;
    /* Clock again runs from 0 through 1 */
    #declare BallRot = <1*200, Clock*150, 0>
    /* The ball was rotated x*200 before, now rotate it 150 degrees
     * around the y axis. */
  #break
  /* ...part 3 inserted here... */
  #range (3, 4.1) 
  /* You should make the end of the interval a bit larger, otherwise
   * the final frame may not be rendered correctly. */
  #break
#end

You could also have a look at the scene files for my entries in the IRTC
animation rounds - Four Seasons in the Oct-Jan '98 round, and Revenge od
the Dragon Lord in the Apr-Jul '98 round.

Good luck!
