This would be a good opportunity for you to start moving away from using qplot, in favor of ggplot. This will be much easier in the long run, trust me.

Here's a start:

library(scales)
ggplot(data = x,aes(x = factor(filename),y = value)) + 
    geom_bar(aes(fill = factor(variable)),colour = "black",position = 'dodge') + 
    coord_flip() + 
    scale_fill_manual(name = '',
                      labels = c('low',
                                 'Hi',
                                 "Tot"),
                      values = c('#40E0D0',
                                 '#FF6347',
                                 "#C7C7C7")) + 
    scale_y_continuous(labels = percent_format())

For philosophical reasons, I will leave the annotation piece to you...
