Whereas this works in Mathematica 6.03, there is now the error "An improperly formatted option was encountered while reading a GraphicsBox. The option was not in the form of a rule."
This is apparently caused by any graphics directive (such as Hue, Opacity, Thickness), but I was able to reliably work around it by replacing Graphics with HoldForm@Graphics.
There seems to be no problem with Graphics3D markers, and according to the documentation there should be no problem with arbitrary Graphics as plot markers, either. I'm guessing there has been some subtle change in Graphics' inner workings that conflicts with its use in PlotMarkers - but who knows.
Anyway, HoldForm is the cure, in case anyone else stumbles over this issue.

Syd, although your example isn't quite correct, you do have a point!
Your example doesn't work even in Mathematica 6 where the bug is absent: the documentation says we should be able to set the scale s of a graphics object g by specifying {g, s} in PlotMarkers. But if I try this in my example with HoldForm applied to Graphics, it doesn't work.
What does work, though, is to specify the size s of the circle as Circle[{0,0}, Scaled[s]]. This works in Mathematica 6 and 7, with or without HoldForm. For text, you can also put in things like Style ["A",Larger] etc.
I did report the bug, too. A working ListPlot would be nice, wouldn't it?
Clearly, in Mathematica 7 the outmost List does not wrap around all graphics primitives as it does in Mathematica 6, but only around the first one. The closing bracket is misplaced. This leaves the latter primitives bungling.

Sjoerd, thanks for getting to the bottom of this, your workaround really seems to be fool-proof.
