Curiosity with osascript

[John Delacour]

I'm getting a curious result whenever I try to run the simplest osascript

In Terminal I get this

eremita:~ jd$ osascript -e 'return 100'
CFBundle 0x3734b0 </Users/jd/Library/ScriptingAdditions/XSpell.osax> 
(bundle, loaded)
100
eremita:~ jd$

and in BBEdit or Affrus I get the same CFBundle line but without the 
result (100).

Has anyone any idea what's going on?
