Why? They generally didn't get blood on their clothes.

Ditto.

Contact of the paroches with blood wasn't part of the daily avoda. Only YK, par heelem dovor shel tzibbur and par kohen moshiach.

Cleaned twice a year? A source please?

WRT the original question, it could be that it isn't listed amongst avodos koshos because it was such a rare occurance, as opposed to chafina, malika and kamitza which took place regularly.

But is it physically possible to throw a drop of blood 20 amos?
