Since magic is involved, perhaps the design of the cutie mark is chosen (presumably by the Tree of Harmony) based in part on the name and other atributes of the individual. [Example: Applejack has apple in her name and was raised on an apple farm, so the Tree of Harmony chose an apple as her cuite mark.]  The Tree of Harmony might also be able to foresee part of the future. Flim and Flam's name aren't related to their cutie mark, but the do get involved with the apple family and the brothers are virtually inseparable. So they each have part of an apple as their cutie marks.
