When I need to figure out what type of layer I'm working with, I run the following code:

s2t = stringIDToTypeID;
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('layerKind'));
r.putEnumerated(s2t('layer'), s2t('ordinal'), s2t('targetEnum'));
var layerKind = executeActionGet(r).getInteger(p);

the values we can get are:

const kAnySheet             = 0; 
const kPixelSheet           = 1;  
const kAdjustmentSheet      = 2;  
const kTextSheet            = 3;  
const kVectorSheet          = 4;  
const kSmartObjectSheet     = 5;  
const kVideoSheet           = 6;  
const kLayerGroupSheet      = 7;  
const k3DSheet              = 8;  
const kGradientSheet        = 9;  
const kPatternSheet         = 10;  
const kSolidColorSheet      = 11;  
const kBackgroundSheet      = 12;  
const kHiddenSectionBounder = 13;

If you know that you are working with an adjustment layer, then its type can be found like this:

s2t = stringIDToTypeID;
(r = new ActionReference()).putProperty(s2t('property'), p = s2t('adjustment'));
r.putEnumerated(s2t('layer'), s2t('ordinal'), s2t('targetEnum'));
alert(typeIDToStringID(executeActionGet(r).getList(p).getObjectType(0)));

alert("Current Layer is a " + determinelayerkind(layer));
