For a cylinder lying along the x axis you could try this:

#declare Rad = 1;   //Radius
#declare Length = 10;
#declare R = seed(7);

//...

translate <rand(R)*Length, 0, rand(R)*Rad*2-1>
  //That line will place the thing on a "slice" of the cylinder
rotate x*rand(R)*360
  //And that line will rotate it randomly so that it could be anywhere
  //in the cylinder

//...
