Summary:
Under prior versions of OSX, calling CTFontCopyFeatures for a CTFontRef containing the LNUM opentype feature would show three options for kNumberCaseType: 

0: oldstyle figures
1: lining figures
2: no change

in mavericks, only 0 and 2 are available, with the same font.

the problem also manifests itself under advanced typography options in textedit.

Steps to Reproduce:
with the supplied font (or any font using the LNUM opentype feature), compile the following:

    CTFontRef ctf = CTFontCreateWithName(CFSTR("NadyezhdaSLOne-Reg"), 16.0, nil);
    CFArrayRef feats = CTFontCopyFeatures(ctf);
    for (NSDictionary* d in (__bridge NSArray *) feats) {
        if ([d objectForKey:@"CTFeatureTypeIdentifier"] == [NSNumber numberWithInt:21])
            NSLog(@"%@", d);
    }


Expected Results:
{
        CTFeatureTypeExclusive = 1;
        CTFeatureTypeIdentifier = 21;
        CTFeatureTypeName = "Number Case";
        CTFeatureTypeSelectors =         (
                        {
                CTFeatureSelectorIdentifier = 0;
                CTFeatureSelectorName = "Old-Style Figures";
            },
                        {
                CTFeatureSelectorIdentifier = 1;
                CTFeatureSelectorName = "Lining Figures";
            },
                        {
                CTFeatureSelectorDefault = 1;
                CTFeatureSelectorIdentifier = 2;
                CTFeatureSelectorName = "No Change";
            }
        );
    }

Actual Results:
{
        CTFeatureTypeExclusive = 1;
        CTFeatureTypeIdentifier = 21;
        CTFeatureTypeName = "Number Case";
        CTFeatureTypeNameID = "-2200";
        CTFeatureTypeSelectors =         (
                        {
                CTFeatureSelectorIdentifier = 0;
                CTFeatureSelectorName = "Old-Style Figures";
                CTFeatureSelectorNameID = "-2201";
            },
                        {
                CTFeatureSelectorDefault = 1;
                CTFeatureSelectorIdentifier = 2;
                CTFeatureSelectorName = "No Change";
                CTFeatureSelectorNameID = "-2203";
            }
        );
    }

Version:
osx 10.9.1 -- incorrect behavior

osx 10.6.8 -- correct behavior

Notes:
did not have any other versions of osx handy to test

Configuration:
the correct behavior was observed in 10.6, the incorrect behavior showing only two states for NumberCase showed up in 10.9
