I don't really know if serajr made a working version with the following characteristics:
-Dock items WITH
-NO widgets errors (overlapping, cuts)
EDIT: it has the widget overlapping bug :/
In X8 apps section i've found THIS
serajr, if you want, take a look
but this is a xperia arc launcher ics-themed, maybe you can see the code or something
PD: Obviously new Xperia S widgets will not work, as the launcher is based on old versions of the xperia launcher.
