stplot - legend/classes of categorical vairable

I'm getting strange behavior in the bar legend with factors ...
I cut my data into intervals and plotted results using stplot, however now
the levels are not appearing in the same order as levels(factor)...?
For example, I get the same problem here:
library(spacetime)
example(STFDF)
set.seed(42)
gridded(stfdf at sp) = TRUE
stfdf$f = factor(sample(c("a", "b", "c"), 12, replace = TRUE))
levels(stfdf$f)
levels(stfdf$f)<-c('0','(0,5]','(5,25]')
levels(stfdf$f)
library(RColorBrewer)
stplot(stfdf[,,"f"], col.regions = brewer.pal(3, "Accent"))
Thoughts on how to fix this?
I'm not sure what you had expected: do you want them to decrease, in value, from top to bottom? sp::spplot does it the same way stplot does now.
