  In systems exhibiting fluctuation-dominated phase ordering, a single order
parameter does not suffice to characterize the order, and it is necessary to
monitor a larger set. For hard-core sliding particles (SP) on a fluctuating
surface and the related coarse-grained depth (CD) models, this set comprises
the long-wavelength Fourier components of the density profile. We study both
static and dynamic scaling laws obeyed by the Fourier modes $Q_m$ and find that
the mean value obeys the static scaling law $\langle Q_m \rangle \sim
L^{-\phi}f(m/L)$ with $\phi\simeq2/3$ and $\phi \simeq 3/5$ with
Edwards-Wilkinson (EW) and Kardar-Parisi-Zhang (KPZ) surface evolution
respectively. The full probability distribution $P(Q_m)$ exhibits scaling as
well. Further, time-dependent correlation functions such as the steady state
auto-correlation and cross-correlations of order parameter components are
scaling functions of $t/L^z$, where $L$ is the system size and $z$ is the
dynamic exponent with $z=2$ for EW and $z=3/2$ for KPZ surface evolution. In
addition we find that the CD model shows temporal intermittency, manifested in
the dynamical structure functions of the density and a weak divergence of the
flatness as the scaled time approaches zero.
