Aha! The problem is that you need a float value to specify which moment 
in time POV-Ray will assign the vector. Try this instead:

#declare myspline=spline{
   linear_spline
   #declare index=0;
   #while (index<100)
     index MyVectors[index]
     #declare index=index+1;
   #end
}

Note the "index" in front of the MyVectors[index].
