Getting “Error -1,752” when trying to save in Script Editor

applescript

I'm trying to edit a script in ~/Library/Scripts/Applications/Mail. When I attempt to save from Script Editor I get The document "Reply.scpt" could not be saved. (Error -1,752). It doesn't seem to be a permissions issue because I can edit and save the file in BBEdit (it's a plain text file).

I'm running Script Editor 2.8.1 under OS X 10.11.1 on a late 2015 iMac.

The problem is that the file is a plain text file. When I originally created the file in 2007, Script Editor could apparently save uncompiled .scpt files. Now, however, as described in Can't save AppleScript file when created by touch, .scpt files must be compiled. Uncompiled files can be saved with the .applescript extension.

I know this is nearly a duplicate of the question linked above, but I added it because as of OS X 10.11 El Capitan Script Editor gives an error number for this problem. I couldn't find any other references to this error number so I thought it was worthwhile to get the error number in a question title.
