I have some 1200 dpi scans that need to be scaled down, sharpened

i am curious for the reason for saving at the 50% quality setting.
fiddling with the quality setting is good to do if you are trying to
improve the load speed of a web page and perhaps to save disc space if
this is a problem.
i guess i would like to know what the purpose is for the image.
Yup, just trying to make the document a little lighter weight. The
basic purpse of the doc is as a series of reference charts and
tables that will be hyperlinked -- eliminating the need to
repeatedly refer to the paper book that the scans were taken from.
Nothing especially exciting, but I am learning about different
practices for high quality image manipulation in The GIMP.
Should the operations be performed in the order above or would it be
better to scale->save as 50% qual jpg->unsharp mask->save as 100%
saving should be only one step and the last step. the unsharp mask
should be the second to the last step. if sharpening is necessary, it
should be done on each size that you save. so in short:
