Your “Streets of Italy” does the same thing, you can’t use mortars as they explode them they hit the skybox.
Make sure you have ‘surfaceparm sky’ in the script.

i had streets of italy on my mind 
here is my sky shader:
textures/italy/wolken
{
qer_editorimage textures/italy/qer_sky.tga
q3map_lightImage textures/italy/sky_detail1.tga
q3map_sunExt 0.4 0.4 0.45 400 -30 45 16 12
q3map_skyLight 140 3
surfaceparm sky
surfaceparm noimpact
surfaceparm nolightmap
surfaceparm nodlight
skyparms textures/italy/env/sky 1500 -
nopicmip
q3map_nofog
}
as you can see, there is a surfaceparm sky…

Seems like you have every thing you need. I had this problem once too, or some thing simular but I can’t remember what I added to the script to make it work.
Is the skybox fully chaulked? And then did you face select + texture with your sky?
