I tweaked this a little bit, mostly to change the /use to /cast in the PostMacro since it was clipping the Ray of Frost cast.

Sequences['ST_MFrost'] = {
author='Sceptre',
specID=64,
helpTxt = 'Talents: 1322112',
icon='Spell_Frost_FrostBolt02',
PreMacro=[[
/cast [nopet,nomod] Summon Water Elemental
]],
"/cast [nochanneling] Rune of Power",
"/cast [nochanneling] Ray of Frost",
"/cast [nochanneling] Frost Bomb",
"/cast [nochanneling] Frozen Orb",
"/cast [nochanneling] Frozen Touch",
"/cast [nochanneling] Ice Lance",
"/cast [nochanneling] Flurry",
"/cast [nochanneling] Ice Lance",
"/cast [nochanneling] Glacial Spike",
"/cast [nochanneling] Frostbolt",
PostMacro=[[
/startattack
/use [combat]13
/use [combat]14
/cast [nochanneling] Ice Barrier
/cast [nochanneling] Ice Floes
/cast [nochanneling] Icy Veins
/cast [nochanneling] Frozen Orb
]],
}

Where should I add Ebonbolt?
