Had this problem before, because of 0.3d.

Change:
if( sscanf( params, "us[128]", iVictim, szOption ) )
To:
if( sscanf( params, "ds[128]", iVictim, szOption ) )

Somehow 0.3d settings for sscanf are messed up (changed).
This worked for me, give it a try and let me know

EDIT:

Oh and doing this you're not getting all the parameters needed.
Since you're looking for 3:
- id
- option (%s)
- value (%i)
