In the following lines, you are unconditionally setting zstyles
globally.  This is inadvisable as it will override user settings
and interfere with other completion functions.  If you need to set
them, you should probably only set the zstyles for something like
':completion:*:complete:sisu:*', and only if the user hasn't set them.
Without knowing anything about how sisu command-line arguments work,
I'd assume that you don't really need to set these.

For example, you may want to use the -M option to _arguments instead.

Probably you want to tack the _files onto the _arguments call, like this
  '(- *)--help[display help information]' \
  ':SiSU files:_files -g "*.(sst|ssm)"'

or

  '(- *)--help[display help information]' \
  '*:SiSU files:_files -g "*.(sst|ssm)"'
