comma, no comma... documentation at 
http://www.povray.org/documentation/view/3.6.1/286/ is a little a 
ambiguous ! the syntax is :
SOR:
    sor
    {
        Number_Of_Points, <Point_1>, <Point_2>, ... <Point_n>
        [ open ] [SOR_MODIFIERS...]
    }
SOR_MODIFIER:
    sturm | OBJECT_MODIFIER

as you can see, there are comma between <Point_1> and <Point_2> and ...

but, in a simple vase exemple :
 #declare Vase = sor {
  7,
  <0.000000, 0.000000>
  <0.118143, 0.000000>
  <0.620253, 0.540084>
  <0.210970, 0.827004>
  <0.194093, 0.962025>
  <0.286920, 1.000000>
  <0.468354, 1.033755>
  open
 }
there is NO comma... and as Warp say : no need at all !

have fun
