Your problem may be how you're setting the attribute. To set up only the bit
you need to use attribute|=(on<<bit) where 'on' is the number of the
setting, such as, for transparency settings, 0 for 0.5 x Back + 0.5 x
Forward, etc, and bit is the first bit in the setting you're changing, so
28, for Semi-transparency rate.

For this you must use GsSortSprite, not GsSortFastSprite.

Here:
attribute|=(1<<30)
attribute|=(setting<<28) /* where setting is the number related to the
transparency rate */
