You don't need to use/have the count to set it to 0. Once this is done, the weapon will disappear, but like I said it may reappear at new round. Take a look at my plugin to check what I did.

set_pdata_int( ent , m_iCount , 0 , XoCArmoury )

Also not sure but the player is touching the ent so it may get picked up before it is set to 0 so this may be a bad idea. Just kill the entity. Maybe set to 0 then return PLUGIN_HANDLED?
