Create two lists, one with even and one with odd numbers. Then sort each and combine. I copy-pasted your data into a csv file.
import arcpy, os
testfile = r"C:\GIS\data\testdata\sortme.csv"
outdb = r"C:\GIS\data\testdata\testdatabas.gdb"
outtable = 'sorted2'
arcpy.MakeTableView_management(in_table=testfile, out_view='tview')
arcpy.TableToTable_conversion(in_rows='tview', out_path=outdb, out_name=outtable) #Create table from view
arcpy.TruncateTable_management(os.path.join(outdb,outtable)) #Empty it
fields = ['Layer','Meas', 'ID']
icur = arcpy.da.InsertCursor(os.path.join(outdb,outtable), fields)
rows = [i for i in arcpy.da.SearchCursor('tview', fields)] #List all rows
even = list(filter(lambda x: (x[0]%2==0), rows)) #filter out even Layer numbers (Layer is first element in fields list = index[0]
odd = list(filter(lambda x: (x[0]%2!=0), rows)) #odd
even_sorted = sorted(even, key=lambda x: x[1], reverse=True)
odd_sorted = sorted(odd, key=lambda x: x[1])
both = sorted(even_sorted+odd_sorted, key=lambda x: x[0])
icur = arcpy.da.InsertCursor(os.path.join(outdb,outtable), fields)
for row in both:
icur.insertRow(row)
del icur
