It's generating a PPM file, or so sez GraphicConverter.

It appears to be a problem with the interpreter, and fortunately not 
with the underlying JPEG mechanism.

The problem seems limited to this form:

   export <format> to file <path>

But I just tried the other form shown in the Transcript Dictionary:

   export <imageDescriptor> to file <path> as <format>

...and it seems to work, apparently routing the command to the 
appropriate compressor, e.g.:

    export img 1 to file "mytest2.jpg" as jpeg
    export img "MyImage" to file "mytest2.png" as png

If you want it to work by selection you could use:

    export the selectedObject to file "mytest1.jpg" as "jpeg"
