Not sure, but if you are doing this in an EVT_STC_MODIFIED handler  
you might be able to do it by playing with the bits in SetModEventMask.

Perhaps

SetModEventMask(wx.stc.STC_MOD_DELETETEXT | wx.stc.STC_MOD_DELETETEXT  
| wx.stc.STC_PERFORMED_USER)

should set it so only events performed by the user fire a modify  
event (not tested)

This should work without affecting selection or scroll position (also  
not tested...)

SetTargetStart(pos)
SetTargetEnd(len)
ReplaceTarget(replaceString)
