Paul,I was able to reproduce this bug in Origin and I have reported it to our developers. If a contour plot extends beyond the layer frame the portion of the contour plot extending beyond the layer frame is included in the metafile created by the menu option Edit:Copy Page. This is true even if the Clip Data to Frame checkbox is checked in the Layer Properties dialog box and the graph appears as it should within Origin.
Rather than rescaling a contour plot and then clipping the data to the layer frame to show only a desired portion of the contour plot, you might want to try copy/pasting the relevant portion of the matrix you are interested in to a new sub-matrix and then plotting the new sub-matrix at full scale. This is somewhat involved but it is the only work around that I could envision.

Additional Comment: Eureka!!! Why didn't I think of this earlier?
I have found that exporting the graph as a JPEG or BMP file (select the File:Export Page menu option in Origin when the graph window is active) and then inserting these files into Word (select the Insert:Picture:From File menu option in Word) is quite an effective work around to this bug.
