I want to use a cell count of an integer raster as a variable in Arcgis 10 ModelBuilder (and later in a python script), but can't seem to find how to access this information.

Is there a (python) function that will return a cell count for a particular value? eg. something like

count([raster], value)? 

Or how do I access the count column for a particular value in the raster table?

You could try to access it by reading the attribute table (assuming you have one; if you don't there is also a python function to create one).

# loop through attribute table    
Rows = ARCPY.SearchCursor( shapefile ) 

SomeValue = 'Count' # or some other column header name
for row in Rows:
    val = row.getValue( SomeValue ) 
    print val
