Two comments:
a) A return value of 0 probably is much more common than the XK_ISO_Left_Tab
keysym, so the XK_ISO_Left_Tab check should be first to not have to check both
conditions in the event that ret is 0.
(the compiler might do reordering according to check probability, though,
but OTOH I doubt that it knows which one is more likely)
b) there's another if (ret == 0) *right below*, so why not add the
XK_ISO_Left_Tab check there? Again useless waste of resources...

Thanks for this patch!
