This script
set sourceFolder to choose folder with prompt "Select Source Folder"
set destinationFolder to choose folder with prompt "Select Destination Folder"
set diag to display dialog "Set skip count" default answer "10"
set skipCount to (text returned of diag) as integer
tell application "Finder"
set theFiles to the files of sourceFolder
repeat with n from skipCount to (count of theFiles) by skipCount
duplicateitemn of theFilestofolder the destinationFolder
end repeat
end tell
will prompt you for the source and destination folders (the destination folder must exist already) and then prompt for the number of files to skip.
It will duplicate the selected files from the source to the destination. If you do not want the files to remain in the source folder replace duplicate with move in the script.
To make the above into a script select all the text in the box then right (control) click the selection, select Services->Make New AppleScript.
As with all script gotten from the web make sure you test it out on some dummy files first and make sure you have backups of the data you are working on.
regards
Note this will start with the file at skipCount and increment from there. That is with the skipCount set to 10 the first file moved is file number 10 then 20, 30, etc.
