Try
bpy.context.scene.frame_set()
Operators rely on context so it can get hard to satisfy them (you could also
try making a timeline window visible). You can override context by paying an
optional dict to the operator but I've found this tricky to get right in
practice.
Oh, and welcome to this blender thing,
