plot multiple cumulative percentage graph by groups

I have data looks like: 

zip   ID    count
230   B      12
230   A      10
230   C       9
230   D       5
270   C      10
270   A       9
270   B       8
290   C       9
290   A       8
290   B       6

zip and ID are factor and count is numeric. ID is uniquely associated with count. Within each level of zip, count is in desc order.

How can I create cumulative percentage graphs by each level of zip for count (in this case, I need 3 graphs in one window) and at the same time ticking the x-axis using ID? Also, the x-axis will keep the desc order or count (which means, the largest percentage goes first).

So far I read that ggplot2 has ecdf built-in, but I don't know how to generate multiple graphs there. I tried 

p<-qplot(dat,stat='ecdf',geom='count')+facet_wrap(~zip,ncol=10)

But it didn't work at all.

Can anyone give me a hint?

 ggplot(dat, aes(x=count) )+stat_ecdf()+facet_wrap(~zip,ncol=10)

(Although the ncol argument seems to get ignored.)
